• Coding solution to WAR installation error (Websphere Portal 6.0) ?

  - by Scott Leis

  I have a Websphere Portal application containing several portlets for which I'm currently working on some changes. A week ago, the WAR file produced by Rational Application Developer could be installed on the Portal server with no problems. Yesterday I made some seemingly minor changes to two JSP files and their associated "pagecode" Java files, and attempting to update the WAR on the server (using the Portal Administration web interface) now produces an error message. The WAR upload works, and the system shows me the correct list of portlets in the WAR file, but clicking "Finish" gives me a page with the error message "EJPAQ1319E: Cannot install the selected WAR file. View Details". Clicking the "View Details" link gives me a page with the following text: EJPAQ1319E: Cannot install the selected WAR file. com.ibm.portal.WpsException: EJPAQ1319E: Cannot install the selected WAR file. at com.ibm.wps.portlets.portletmanager.actions.DoInstallWebModuleAction.installPortletFromFormFile(DoInstallWebModuleAction.java:633) at com.ibm.wps.portlets.portletmanager.actions.DoInstallWebModuleAction.doExecute(DoInstallWebModuleAction.java:159) at com.ibm.wps.portlets.adminstruts.actions.BaseAction.execute(BaseAction.java:64) at com.ibm.wps.portlets.struts.WpsRequestProcessor.processActionPerform(WpsRequestProcessor.java:338) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:274) at com.ibm.wps.portlets.struts.WpsStrutsPortlet.processActionPerformed(WpsStrutsPortlet.java:1947) at com.ibm.wps.portlets.struts.WpsStrutsPortlet.actionPerformed(WpsStrutsPortlet.java:1637) at com.ibm.wps.portlets.adminstruts.WpsAdminStrutsPortlet.actionPerformed(WpsAdminStrutsPortlet.java:261) at com.ibm.wps.pe.pc.legacy.SPIPortletInterceptorImpl.handleEvents(SPIPortletInterceptorImpl.java:323) EJPPE0020E: It is not allowed to install a JSR 168 compliant over a 4.x portlet application. com.ibm.wps.command.applications.AppWarFileException: EJPPE0020E: It is not allowed to install a JSR 168 compliant over a 4.x portlet application.

Explanation: A portlet application containing legacy portlets can only be updated with another portlet application that contains legacy portlets. The same is true for standard portlet applications. User Response: Modify the portlet.xml of the application such that it matches the original API type, standard or legacy and try again. However, the "portlet.xml" file has not changed in about a month, and I've done several WAR updates for this application in that time with no problems. The problem seems to be caused by the code changes I did yesterday, but I have no clue why a few lines of code would do this. Any ideas?

• Binding DataTable To GridView, But No Rows In GridViewRowCollection Despite GridView Population?

  - by KSwift87

  Problem: I've coded a GridView in the markup in a page. I have coded a DataTable in the code-behind that takes data from a collection of custom objects. I then bind that DataTable to the GridView. (Specific problem mentioned a couple code-snippets below.) GridView Markup: <asp:GridView ID="gvCart" runat="server" CssClass="pList" AutoGenerateColumns="false" DataKeyNames="ProductID"> <Columns> <asp:BoundField DataField="ProductID" HeaderText="ProductID" /> <asp:BoundField DataField="Name" HeaderText="ProductName" /> <asp:ImageField DataImageUrlField="Thumbnail" HeaderText="Thumbnail"></asp:ImageField> <asp:BoundField DataField="Unit Price" HeaderText="Unit Price" /> <asp:TemplateField HeaderText="Quantity"> <ItemTemplate> <asp:TextBox ID="Quantity" runat="server" Text="<%# Bind('Quantity') %>" Width="25px"></asp:TextBox> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="Total Price" HeaderText="Total Price" /> </Columns> </asp:GridView> DataTable Code-Behind: private void View(List<OrderItem> cart) { DataSet ds = new DataSet(); DataTable dt = ds.Tables.Add("Cart"); if (cart != null) { dt.Columns.Add("ProductID"); dt.Columns.Add("Name"); dt.Columns.Add("Thumbnail"); dt.Columns.Add("Unit Price"); dt.Columns.Add("Quantity"); dt.Columns.Add("Total Price"); foreach (OrderItem item in cart) { DataRow dr = dt.NewRow(); dr["ProductID"] = item.productId.ToString(); dr["Name"] = item.productName; dr["Thumbnail"] = ResolveUrl(item.productThumbnail); dr["Unit Price"] = "$" + item.productPrice.ToString(); dr["Quantity"] = item.productQuantity.ToString(); dr["Total Price"] = "$" + (item.productPrice * item.productQuantity).ToString(); dt.Rows.Add(dr); } gvCart.DataSource = dt; gvCart.DataBind(); gvCart.Width = 500; for (int counter = 0; counter < gvCart.Rows.Count; counter++) { gvCart.Rows[counter].Cells.Add(Common.createCell("<a href='cart.aspx?action=update&prodId=" + gvCart.Rows[counter].Cells[0].Text + "'>Update</a><br /><a href='cart.aspx?action='action=remove&prodId=" + gvCart.Rows[counter].Cells[0].Text + "/>Remove</a>")); } } } Error occurs below in the foreach - the GridViewRowCollection is empty! private void Update(string prodId) { List<OrderItem> cart = (List<OrderItem>)Session["cart"]; int uQty = 0; foreach (GridViewRow gvr in gvCart.Rows) { if (gvr.RowType == DataControlRowType.DataRow) { if (gvr.Cells[0].Text == prodId) { uQty = int.Parse(((TextBox)gvr.Cells[4].FindControl("Quantity")).Text); } } } Goal: I'm basically trying to find a way to update the data in my GridView (and more importantly my cart Session object) without having to do everything else I've seen online such as utilizing OnRowUpdate, etc. Could someone please tell me why gvCart.Rows is empty and/or how I could accomplish my goal without utilizing OnRowUpdate, etc.? When I execute this code, the GridView gets populated but for some reason I can't access any of its rows in the code-behind.

• Rendering a view to a string in MVC, then redirecting -- workarounds?

  - by James S

  Hi -- I can't render a view to a string and then redirect, despite this answer from Feb (after version 1.0, I think) that claims it's possible. I thought I was doing something wrong, and then I read this answer from Haack in July that claims it's not possible. If somebody has it working and can help me get it working, that's great (and I'll post code, errors). However, I'm now at the point of needing workarounds. There are a few, but nothing ideal. Has anybody solved this, or have any comments on my ideas? This is to render email. While I can surely send the email outside of the web request (store info in a db and get it later), there are many types of emails and I don't want to store the template data (user object, a few other LINQ objects) in a db to let it get rendered later. I could create a simpler, serializable POCO and save that in the db, but why? ... I just want rendered text! I can create a new RedirectToAction object that checks if the headers have been sent (can't figure out how to do this -- try/catch?) and, if so, builds out a simple page with a meta redirect, a javascript redirect, and also a "click here" link. Within my controller, I can remember if I've rendered an email and, if so, manually do #2 by displaying a view. I can manually send the redirect headers before any potential email rendering. Then, rather than using the MVC infrastructure to redirecttoaction, I just call result.end. This seems easiest, but really messy. Anything else? EDIT: I've tried Dan's code (very similar to the code from Jan/Feb that I've already tried) and I'm still getting the same error. The only substantial difference I can see is that his example uses a view while I use a partial view. I'll try testing this later with a view. Here's what I've got: Controller public ActionResult Certifications(string email_intro) { //a lot of stuff ViewData["users"] = users; if (isPost()) { //create the viewmodel var view_model = new ViewModels.Emails.Certifications.Open(userContext) { emailIntro = email_intro }; //i've tried stopping this after just one iteration, in case the problem is due to calling it multiple times foreach (var user in users) { if (user.Email_Address.IsValidEmailAddress()) { //add more stuff to the view model specific to this user view_model.user = user; view_model.certification302Summary.subProcessesOwner = new SubProcess_Certifications(RecordUpdating.Role.Owner, null, null, user.User_ID, repository); //more here.... //if i comment out the next line, everything works ok SendEmail(view_model, this.ControllerContext); } } return RedirectToAction("Certifications"); } return View(); } SendEmail() public static void SendEmail(ViewModels.Emails.Certifications.Open model, ControllerContext context) { var vd = context.Controller.ViewData; vd["model"] = model; var renderer = new CustomRenderers(); //i fixed an error in your code here var text = renderer.RenderViewToString3(context, "~/Views/Emails/Certifications/Open.ascx", "", vd, null); var a = text; } CustomRenderers public class CustomRenderers { public virtual string RenderViewToString3(ControllerContext controllerContext, string viewPath, string masterPath, ViewDataDictionary viewData, TempDataDictionary tempData) { //copy/paste of dan's code } } Error [HttpException (0x80004005): Cannot redirect after HTTP headers have been sent.] System.Web.HttpResponse.Redirect(String url, Boolean endResponse) +8707691 Thanks, James

• Adding interactions to admin pages generated by the admin generator

  - by Stick it to THE MAN

  I am using Symfony 1.2.9 (with Propel ORM) to create a website. I have started using the admin generator to implement the admin functionality. I have come accross a slight 'problem' however. My models are related (e.g. one table may have several 1:N relations and N:N relations). I have not found a way to address this satisfactorily yet. As a tactical solution (for list views), I have decided to simply show the parent object, and then add interactions to show the related objects. I'll use a Blog model to illustrate this. Here are the relationships for a blog model: N:M relationship with Blogroll (models a blog roll) 1:N relationship with Blogpost (models a post submitted to a blog) I had originally intended on displaying the (paged) blogpost list for a blog,, when it was selected, using AJAX, but I am struggling enough with the admin generator as it is, so I have shelved that idea - unless someone is kind enough to shed some light on how to do this. Instead, what I am now doing (as a tactical/interim soln), is I have added interactions to the list view which allow a user to: View a list of the blog roll for the blog on that row View a list of the posts for the blog on that row Add a post for the blog on tha row In all of the above, I have written actions that will basically forward the request to the approriate action (admin generated). However, I need to pass some parameters (like the blog id etc), so that the correct blog roll or blog post list etc is returned. I am sure there is a better way of doing what I want to do, but in case there isn't here are my questions: How may I obtain the object that relates to a specific row (of the clicked link) in the list view (e.g. the blog object in this example) Once I have the object, I may choose to extract various fields: id etc. How can I pass these arguments to the admin generated action ? Regarding the second question, my guess is that this may be the way to do it (I may be wrong) public function executeMyAddedBlogRollInteractionLink(sfWebRequest $request) { // get the object *somehow* (I'm guessing this may work) $object = $this->getRoute()->getObject(); // retrieve the required parameters from the object, and build a query string $query_str=$object->getId(); //forward the request to the generated code (action to display blogroll list in this case) $this->forward('backendmodulename',"getblogrolllistaction?params=$query_string"); } This feels like a bit of a hack, but I'm not sure how else to go about it. I'm also not to keen on sending params (which may include user_id etc via a GET, even a POST is not that much safer, since it is fairly sraightforward to see what requests a browser is making). if there is a better way than what I suggest above to implement this kind of administration that is required for objects with 1 or more M:N relationships, I will be very glad to hear the "recommended" way of going about it. I remember reading about marking certain actions as internal. i.e. callable from only within the app. I wonder if that would be useful in this instance?

• Android Augmented Reality

  - by Azooz Totti

  I'm working on my first Android Augmented Reality application. The application works pretty good if the ARActivity runs as the first class (android.intent.category.LAUNCHER) in the manifest file. But when I added a splash screen which means the ARActivity will be the second to run(android.intent.category.DEFAULT), the camera seems not detecting the marker. I believe the problem is all in the manifest file. Any suggestions ? Thanks This is the manifest.xml <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.ar.armarkers" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera.autofocus" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".Splash" android:screenOrientation="landscape" android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.ar.armarkers.MainActivity" android:clearTaskOnLaunch="true" android:label="@string/title_activity_main" android:noHistory="true" android:screenOrientation="landscape" > <intent-filter> <action android:name="com.ar.armarkers.MAINACTIVITY" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> </application> </manifest> MainActivity.java import edu.dhbw.andar.ARObject; import edu.dhbw.andar.ARToolkit; import edu.dhbw.andar.AndARActivity; import edu.dhbw.andar.exceptions.AndARException; import edu.dhbw.andar.pub.CustomRenderer; import android.os.Bundle; import android.util.Log; public class MainActivity extends AndARActivity { private ARObject someObject; private ARToolkit artoolkit; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); CustomRenderer renderer = new CustomRenderer(); setNonARRenderer(renderer); try { artoolkit = getArtoolkit(); someObject = new CustomObject1("test", "marker16.pat", 80.0, new double[] { 0, 0 }); artoolkit.registerARObject(someObject); someObject = new CustomObject2 ("test", "marker17.patt", 80.0, new double[]{0,0}); artoolkit.registerARObject(someObject); } catch (AndARException ex) { System.out.println(""); } startPreview(); } public void uncaughtException(Thread thread, Throwable ex) { // TODO Auto-generated method stub Log.e("AndAR EXCEPTION", ex.getMessage()); finish(); } } Splash.java import android.app.Activity; import android.app.ProgressDialog; import android.content.Intent; import android.os.Bundle; import android.view.Gravity; public class Splash extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.splash); Thread timer = new Thread() { public void run() { try { sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } finally { Intent i = new Intent(getApplicationContext(), MainActivity.class); startActivity(i); } } }; timer.start(); } }

• JPA IndirectSet changes not reflected in Spring frontend

  - by Jon

  I'm having an issue with Spring JPA and IndirectSets. I have two entities, Parent and Child, defined below. I have a Spring form in which I'm trying to create a new Child and link it to an existing Parent, then have everything reflected in the database and in the web interface. What's happening is that it gets put into the database, but the UI doesn't seem to agree. The two entities that are linked to each other in a OneToMany relationship like so: @Entity @Table(name = "parent", catalog = "myschema", uniqueConstraints = @UniqueConstraint(columnNames = "ChildLinkID")) public class Parent { private Integer id; private String childLinkID; private Set<Child> children = new HashSet<Child>(0); @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "id", unique = true, nullable = false) public Integer getId() { return this.id; } public void setId(Integer id) { this.id = id; } @Column(name = "ChildLinkID", unique = true, nullable = false, length = 6) public String getChildLinkID() { return this.childLinkID; } public void setChildLinkID(String childLinkID) { this.childLinkID = childLinkID; } @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "parent") public Set<Child> getChildren() { return this.children; } public void setChildren(Set<Child> children) { this.children = children; } } @Entity @Table(name = "child", catalog = "myschema") public class Child extends private Integer id; private Parent parent; @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "id", unique = true, nullable = false) public Integer getId() { return this.id; } public void setId(Integer id) { this.id = id; } @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "ChildLinkID", referencedColumnName = "ChildLinkID", nullable = false) public Parent getParent() { return this.parent; } public void setParent(Parent parent) { this.parent = parent; } } And of course, assorted simple properties on each of them. Now, the problem is that when I edit those simple properties from my Spring interface, everything works beautifully. I can persist new entities of these types and they'll appear when using the JPATemplate to do a find on, say, all Parents (getJpaTemplate().find("select p from Parent p")) or on individual entities by ID or another property. The problem I'm running into is that now, I'm trying to create a new Child linked to an existing Parent through a link from the Parent's page. Here's the important bits of the Controller (note that I've placed the JPA foo in the controller here to make it clearer; the actual JpaDaoSupport is actually in another class, appropriately tiered): protected Object formBackingObject(HttpServletRequest request) throws Exception { String parentArg = request.getParameter("parent"); int parentId = Integer.parseInt(parentArg); Parent parent = getJpaTemplate().find(Parent.class, parentId); Child child = new Child(); child.setParent(parent); NewChildCommand command = new NewChildCommand(); command.setChild(child); return command; } protected ModelAndView onSubmit(Object cmd) throws Exception { NewChildCommand command = (NewChildCommand)cmd; Child child = command.getChild(); child.getParent().getChildren().add(child); getJpaTemplate().merge(child); return new ModelAndView(new RedirectView(getSuccessView())); } Like I said, I can run through the form and fill in the new values for the Child -- the Parent's details aren't even displayed. When it gets back to the controller, it goes through and saves it to the underlying database, but the interface never reflects it. Once I restart the app, it's all there and populated appropriately. What can I do to clear this up? I've tried to call extra merges, tried refreshes (which gave a transaction exception), everything short of just writing my own database access code. I've made sure that every class has an appropriate equals() and hashCode(), have full JPA debugging on to see that it's making appropriate SQL calls (it doesn't seem to make any new calls to the Child table) and stepped through in the debugger (it's all in IndirectSets, as expected, and between saving and displaying the Parent the object takes on a new memory address). What's my next step?

Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER"); registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0)); registrationIntent.putExtra("sender",Sender_ID); startService(registrationIntent); I've declared the service in the manifest file inside the application tag. <service android:name="com.pack.gcm.MyIntentService" android:enabled="true"/> I placed a breakpoint in my IntentService class but it never goes there.But if I declare my registrationIntent like this Intent registrationIntent = new Intent(getApplicationContext(),com.pack.gcm.MyIntentService); It works and goes to the breakpoint I've placed but intent.getAction() contains null and hence it doesn't go into the if condition placed after those lines. It says 07-08 02:10:03.755: W/ActivityManager(60): Unable to start service Intent { act=com.google.android.c2dm.intent.REGISTER (has extras) }: not found in the logcat.

  I have a list of objects that are organized in a tree using a Depth property: public class Quota { [Range(0, int.MaxValue, ErrorMessage = "Please enter an amount above zero.")] public int Amount { get; set; } public int Depth { get; set; } [Required] [RegularExpression("^[a-zA-Z]+$")] public string Origin { get; set; } // ... another properties with validation attributes } For data example (amount - origin) 100 originA 200 originB 50 originC 150 originD the model data looks like: IList<Quota> model = new List<Quota>(); model.Add(new Quota{ Amount = 100, Depth = 0, Origin = "originA"); model.Add(new Quota{ Amount = 200, Depth = 0, Origin = "originB"); model.Add(new Quota{ Amount = 50, Depth = 1, Origin = "originC"); model.Add(new Quota{ Amount = 150, Depth = 1, Orinig = "originD"); Editing of the list Then I use Editing a variable length list, ASP.NET MVC 2-style to raise editing of the list. Controller actions QuotaController.cs: public class QuotaController : Controller { // // GET: /Quota/EditList public ActionResult EditList() { IList<Quota> model = // ... assigments as in example above; return View(viewModel); } // // POST: /Quota/EditList [HttpPost] public ActionResult EditList(IList<Quota> quotas) { if (ModelState.IsValid) { // ... save logic return RedirectToAction("Details"); } return View(quotas); // Redisplay the form with errors } // ... other controller actions } View EditList.aspx: <%@ Page Title="" Language="C#" ... Inherits="System.Web.Mvc.ViewPage<IList<Quota>>" %> ... <h2>Edit Quotas</h2> <%=Html.ValidationSummary("Fix errors:") %> <% using (Html.BeginForm()) { foreach (var quota in Model) { Html.RenderPartial("QuotaEditorRow", quota); } %> <% } %> ... Partial View QuotaEditorRow.ascx: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Quota>" %> <div class="quotas" style="margin-left: <%=Model.Depth*45 %>px"> <% using (Html.BeginCollectionItem("Quotas")) { %> <%=Html.HiddenFor(m=>m.Id) %> <%=Html.HiddenFor(m=>m.Depth) %> <%=Html.TextBoxFor(m=>m.Amount, new {@class = "number", size = 5})%> <%=Html.ValidationMessageFor(m=>m.Amount) %> Origin: <%=Html.TextBoxFor(m=>m.Origin)%> <%=Html.ValidationMessageFor(m=>m.Origin) %> ... <% } %> </div> Business rule validation How do I implement validation of business rule: Amount of quota and sum of amounts of nested quotas should equal (e.a. 200 = 50 + 150 in example)? I want to appropriate inputs Html.TextBoxFor(m=>m.Amount) be highlighted red if the rule is broken for it. In example if user enters not 200, but 201 - it should be red on submit. Using sever validation only. Thanks a lot for any advise.

For example, if I go to login-guest.php, I would put the default values for username and password and then have a jquery click event that automatically logs them in using $("#btn-login").trigger('click'); The problem is that the session controller automatically goes back to login.php if the session has timed out and I'm not sure how I could go about achieving this. Any help would be much appreciated!

• How to get the selected option value of a drop down box in PHP code

  - by Angeline Aarthi

  I have a dropdown box which lists a set of logos,like flower,butterfly etc. <p class="title1">Logo</p> <select name="logoMenu" class="select" size="7"> <?php foreach($logos as $logo):?> <option id="<?php echo $logo['Subproperty']['id'];?>" value="<?php echo $logo['Subproperty']['values'];?>"><?php echo $logo['Subproperty']['values'];?> </option> <?php endforeach;?> </select> Suppose If I select the logo 'Flower' from the drop down box, I want the flower pic to be displayed in a div.This is the div that I have to display the pictures. <div id="theme_logos" class="float_left spaceleft" style="display:none;"> <?php foreach($defaultLogos as $logo): //if($logo['Subproperty']['values']==clicked option value){?> <img height="50" width="50" src="/FormBuilder/app/webroot/img/themes/<?php echo $logo['Subproperty']['images'];?>" class="float_left user_profile_image user_profile_image" alt="Default50"/> <?php endforeach;?> </div> The problem with this code is that it displaya all the pictures found in the table. Because im My controller code, I give only the property id as that of 'Logo',but do not give which logo. $this->set('defaultLogos',$this->Subproperty->find('all',array('conditions'=>array('Subproperty.property_id'=>1,'Subproperty.values'=>"Flower")))); Here I have hard coded as 'flower' so that I get the flower picture alone.. If I select the logo from the drop down box, how to pass that selected value to the controller code? Or if I get the selected logo name thro' jquery,how to use that value in the if condition inside the for each loop? someone help me out with this.. I'm using CakePHP framework. $("#logoMenu option").click(function(){ selectedLogo=$(this).attr("value"); $('#subproperty_id').val($(this).attr("id")); if(selectedLogo=="Your logo"){ $("#themes_upload").show(); } else{ alert(selectedLogo); $("#themes_upload").hide(); $("#theme_logos").show(); } }); EDIT Now I have tried an ajax post where I pass the selected logo to the same action of the controller. I get the value when I alert the passed value in the success function of the ajax function. I the picture doesn't appear. $("#logoMenu option").click(function(){ selectedLogo=$(this).attr("value"); $('#subproperty_id').val($(this).attr("id")); if(selectedLogo=="Your logo"){ $("#themes_upload").show(); } else{ alert(selectedLogo); $.ajax({ type: "POST", url: "http://localhost/FormBuilder/index.php/themes/themes/", async: false, data: "selectedLogo="+selectedLogo, success: function(msg){ alert( "Data Saved: " + msg); } }); $("#themes_upload").hide(); $("#theme_logos").show(); } }); function themes(){ $this->set('themes',$this->Theme->find('all')); $logo=$this->params['form']['selectedLogo']; echo "logo:".$logo; $this->set('defaultLogos',$this->Subproperty->find('all',array('conditions'=>array('Subproperty.property_id'=>1,'Subproperty.values'=>$logo)))); } But when I trry to display the img in the page,it doesn't appear. Is it because the div show command is after the ajax request?

• When Clearing an ObservableCollection, There are No Items in e.OldItems

  - by cplotts

  I have something here that is really catching me off guard. I have an ObservableCollection of T that is filled with items. I also have an event handler attached to the CollectionChanged event. When you Clear the collection it causes an CollectionChanged event with e.Action set to NotifyCollectionChangedAction.Reset. Ok, that's normal. But what is weird is that neither e.OldItems or e.NewItems has anything in it. I would expect e.OldItems to be filled with all items that were removed from the collection. Has anyone else seen this? And if so, how have they gotten around it? Some background: I am using the CollectionChanged event to attach and detach from another event and thus if I don't get any items in e.OldItems ... I won't be able to detach from that event. CLARIFICATION: I do know that the documentation doesn't outright state that it has to behave this way. But for every other action, it is notifying me of what it has done. So, my assumption is that it would tell me ... in the case of Clear/Reset as well. Below is the sample code if you wish to reproduce it yourself. First off the xaml: <Window x:Class="ObservableCollection.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" > <StackPanel> <Button x:Name="addButton" Content="Add" Width="100" Height="25" Margin="10" Click="addButton_Click"/> <Button x:Name="moveButton" Content="Move" Width="100" Height="25" Margin="10" Click="moveButton_Click"/> <Button x:Name="removeButton" Content="Remove" Width="100" Height="25" Margin="10" Click="removeButton_Click"/> <Button x:Name="replaceButton" Content="Replace" Width="100" Height="25" Margin="10" Click="replaceButton_Click"/> <Button x:Name="resetButton" Content="Reset" Width="100" Height="25" Margin="10" Click="resetButton_Click"/> </StackPanel> </Window> Next, the code behind: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using System.Collections.ObjectModel; namespace ObservableCollection { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public Window1() { InitializeComponent(); _integerObservableCollection.CollectionChanged += new System.Collections.Specialized.NotifyCollectionChangedEventHandler(_integerObservableCollection_CollectionChanged); } private void _integerObservableCollection_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e) { switch (e.Action) { case System.Collections.Specialized.NotifyCollectionChangedAction.Add: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Move: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Remove: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Replace: break; case System.Collections.Specialized.NotifyCollectionChangedAction.Reset: break; default: break; } } private void addButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.Add(25); } private void moveButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.Move(0, 19); } private void removeButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.RemoveAt(0); } private void replaceButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection[0] = 50; } private void resetButton_Click(object sender, RoutedEventArgs e) { _integerObservableCollection.Clear(); } private ObservableCollection<int> _integerObservableCollection = new ObservableCollection<int> { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 }; } }

• Best way to add an extra (nested) form in the middle of a tabbed form

  - by Scharrels

  I've got a web application, consisting mainly of a big form with information. The form is split into multiple tabs, to make it more readable for the user: <form> <div id="tabs"> <ul> <li><a href="#tab1">Tab1</a></li> <li><a href="#tab2">Tab2</a></li> </ul> <div id="tab1">A big table with a lot of input rows</div> <div id="tab2">A big table with a lot of input rows</div> </div> </form> The form is dynamically extended (extra rows are added to the tables). Every 10 seconds the form is serialized and synchronized with the server. I now want to add an interactive form on one of the tabs: when a user enters a name in a field, this information is sent to the server and an id associated with that name is returned. This id is used as an identifier for some dynamically added form fields. A quick sketchup of such a page would look like this: <form action="bigform.php"> <div id="tabs"> <ul> <li><a href="#tab1">Tab1</a></li> <li><a href="#tab2">Tab2</a></li> </ul> <div id="tab1">A big table with a lot of input rows</div> <div id="tab2"> <div class="associatedinfo"> <p>Information for Joe</p> <ul> <li><input name="associated[26][]" /></li> <li><input name="associated[26][]" /></li> </ul> </div> <div class="associatedinfo"> <p>Information for Jill</p> <ul> <li><input name="associated[12][]" /></li> <li><input name="associated[12][]" /></li> </ul> </div> <div id="newperson"> <form action="newform.php"> <p>Add another person:</p> <input name="extra" /><input type="submit" value="Add" /> </form> </div> </div> </div> </form> The above will not work: nested forms are not allowed in HTML. However, I really need to display the form on that tab: it's part of the functionality of that page. I also want the behaviour of a separate form: when the user hits return in the form field, the "Add" submit button is pressed and a submit action is triggered on the partial form. What is the best way to solve this problem?

• Suggestions on how to map from Domain (ORM) objects to Data Transfer Objects (DTO)

  - by FryHard

  The current system that I am working on makes use of Castle Activerecord to provide ORM (Object Relational Mapping) between the Domain objects and the database. This is all well and good and at most times actually works well! The problem comes about with Castle Activerecords support for asynchronous execution, well, more specifically the SessionScope that manages the session that objects belong to. Long story short, bad stuff happens! We are therefore looking for a way to easily convert (think automagically) from the Domain objects (who know that a DB exists and care) to the DTO object (who know nothing about the DB and care not for sessions, mapping attributes or all thing ORM). Does anyone have suggestions on doing this. For the start I am looking for a basic One to One mapping of object. Domain object Person will be mapped to say PersonDTO. I do not want to do this manually since it is a waste. Obviously reflection comes to mind, but I am hoping with some of the better IT knowledge floating around this site that "cooler" will be suggested. Oh, I am working in C#, the ORM objects as said before a mapped with Castle ActiveRecord. Example code: By @ajmastrean's request I have linked to an example that I have (badly) mocked together. The example has a capture form, capture form controller, domain objects, activerecord repository and an async helper. It is slightly big (3MB) because I included the ActiveRecored dll's needed to get it running. You will need to create a database called ActiveRecordAsync on your local machine or just change the .config file. Basic details of example: The Capture Form The capture form has a reference to the contoller private CompanyCaptureController MyController { get; set; } On initialise of the form it calls MyController.Load() private void InitForm () { MyController = new CompanyCaptureController(this); MyController.Load(); } This will return back to a method called LoadComplete() public void LoadCompleted (Company loadCompany) { _context.Post(delegate { CurrentItem = loadCompany; bindingSource.DataSource = CurrentItem; bindingSource.ResetCurrentItem(); //TOTO: This line will thow the exception since the session scope used to fetch loadCompany is now gone. grdEmployees.DataSource = loadCompany.Employees; }, null); } } this is where the "bad stuff" occurs, since we are using the child list of Company that is set as Lazy load. The Controller The controller has a Load method that was called from the form, it then calls the Asyc helper to asynchronously call the LoadCompany method and then return to the Capture form's LoadComplete method. public void Load () { new AsyncListLoad<Company>().BeginLoad(LoadCompany, Form.LoadCompleted); } The LoadCompany() method simply makes use of the Repository to find a know company. public Company LoadCompany() { return ActiveRecordRepository<Company>.Find(Setup.company.Identifier); } The rest of the example is rather generic, it has two domain classes which inherit from a base class, a setup file to instert some data and the repository to provide the ActiveRecordMediator abilities.

• using ajax to post comments in cakephp results in 404 error, but no errors locally?

  - by Paul

  Using an ajax helper created for use with Jquery I've created a form that posts comments to "/comments/add", and this works as expected on my local wamp server but not on my production server. On my production server I get a '404 error, cannot find /comments/add'. I've spent quite a bit of time searching for a resolution with no luck so far. I've focused on trying to identify a gap but nothing jumps out at me. Here are some observations: works as expected on local wamp server requestHandler is listed as component files on both local and production server are the same controllers folder has write access autoLayout and autoRender are both set to false Here is the form in my view: <div class="comments form"> <?php echo $ajax->form('/comments/add', 'tournament', array('url' => '/comments/add', 'update' => 'Comments', 'indicator' => 'commentSaved'));?> <fieldset> <legend><?php __('Add Comment');?></legend> <div id="commentSaved" style="display: none; float: right;"> <h2>Loading...</h2> </div> <?php echo $form->hidden('Comment.foreign_id', array('value' => $tournament['Tournament']['id'])); echo $form->hidden('Comment.belongs_to', array('value' => 'Tournament')); echo $form->input('Comment.name'); echo $form->input('Comment.email'); echo $form->input('Comment.web', array('value' => 'http://')); echo $form->input('Comment.content'); ?> </fieldset> <?php echo $form->end('Submit');?> </div> And here is my 'comment's controller add action: function add() { if($this->RequestHandler->isAjax()) { $this->autoLayout = false; $this->autoRender=false; $this->Comment->recursive =-1; $commentInfos = $this->Comment->findAllByIp($_SERVER['REMOTE_ADDR']); $spam = FALSE; foreach($commentInfos as $commentInfo) { if ( time() - strtotime($commentInfo['Comment']['created']) < 180) { $spam = TRUE; } } if ($spam === FALSE) { if (!empty($this->data)) { $this->data['Comment']['ip'] = $_SERVER['REMOTE_ADDR']; $this->Comment->create(); if ($this->Comment->save($this->data)) { $this->Comment->recursive =-1; $comments = $this->Comment->findAll(array('Comment.foreign_id' => $this->data['Comment']['foreign_id'], 'Comment.belongs_to' => $this->data['Comment']['belongs_to'], 'Comment.status' =>'approved')); $this->set(compact('comments')); $this->viewPath = 'elements'.DS.'posts'; $this->render('comments'); } } } else { $this->Comment->recursive =-1; $comments = $this->Comment->findAll(array('Comment.foreign_id' => $this->data['Comment']['foreign_id'], 'Comment.belongs_to' => $this->data['Comment']['belongs_to'], 'Comment.status' =>'approved')); $this->set(compact('comments')); $this->viewPath = 'elements'.DS.'posts'; $this->render('spam'); } } else { $this->Session->setFlash(__('Invalid Action. Please view a post to add a comment.', true)); $this->redirect(array('controller' => 'pages', 'action'=>'display', 'home')); } } As you can see I've made sure that 'autoLayout' and 'autoRender' are set to false, but in Firebug I still get a 404 error stating /comments/add cannot be found on the production server. I should also point out that I'm using jquery, jquery.form and jquery.editable as well as a ajax helper created to be used with jquery. Any help or even suggestions about how to trouble shoot this is really appreciated. Cheers, Paul

I used the tabBar template provided by xcode no modifications.

In the DAO class, I was trying to execute a native sql as follows: SELECT * FROM product ORDER BY unitprice ASC LIMIT 6 OFFSET 0 But the system throws an exception. org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63) org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:544) com.dao.ProductDAO.listProducts(ProductDAO.java:15) com.dataobjects.impl.ProductDoImpl.listProducts(ProductDoImpl.java:26) com.action.ProductAction.showProducts(ProductAction.java:53) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) application-context.xml is show below <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" p:location="/WEB-INF/jdbc.properties" /> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" p:driverClassName="${jdbc.driverClassName}" p:url="${jdbc.url}" p:username="${jdbc.username}" p:password="${jdbc.password}" /> <!-- Hibernate SessionFactory --> <!-- class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"--> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource"> <ref local="dataSource"/> </property> <property name="configLocation"> <value>WEB-INF/classes/hibernate.cfg.xml</value> </property> <property name="configurationClass"> <value>org.hibernate.cfg.AnnotationConfiguration</value> </property> <!-- <property name="annotatedClasses"> <list> <value>com.pojo.Product</value> <value>com.pojo.User</value> <value>com.pojo.UserLogin</value> </list> </property> --> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> </bean> <!-- User Bean definitions --> <bean name="/logincheck" class="com.action.LoginAction"> <property name="userDo" ref="userDo" /> </bean> <bean id="userDo" class="com.dataobjects.impl.UserDoImpl" > <property name="userDAO" ref="userDAO" /> </bean> <bean id="userDAO" class="com.dao.UserDAO" > <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean name="/listproducts" class="com.action.ProductAction"> <property name="productDo" ref="productDo" /> </bean> <bean id="productDo" class="com.dataobjects.impl.ProductDoImpl" > <property name="productDAO" ref="productDAO" /> </bean> <bean id="productDAO" class="com.dao.ProductDAO" > <property name="sessionFactory" ref="sessionFactory" /> </bean> And DAO class is public class ProductDAO extends HibernateDaoSupport{ public List listProducts(int startIndex, int incrementor) { org.hibernate.Session session = getHibernateTemplate().getSessionFactory().getCurrentSession(); String queryString = "SELECT * FROM product ORDER BY unitprice ASC LIMIT 6 OFFSET 0"; List list = null; try{ session.beginTransaction(); org.hibernate.Query query = session.createQuery(queryString); list = query.list(); session.getTransaction().commit(); } catch(Exception e) { e.printStackTrace(); } finally { session.close(); } return list; } public List getProductCount() { String queryString = "SELECT COUNT(*) FROM Product"; return getHibernateTemplate().find(queryString); } } Any thoughts to fix it up?

• What broke in this Javascript 1.2 snippet?

  - by Rob Kelley

  A friend has pointed me to his old website and says "the submit form just stopped working a while ago. I'm sure it's something simple." The form asks a child for a certain word from a book, and based on the answer, it should redirect the child to a success page or a failure page. It's using Javascript 1.2, circa 2001. You can see this form in in-action at: http://www.secrethidingplaces.com/login1.html Any idea why it's failing? The HTML does this: <script src="password.js" type="text/javascript" language="JavaScript1.2"> </script> <script type="text/javascript" language="JavaScript1.2"> <!-- function showRightPage () { return window.location.href = "extra.html" ; } function showWrongPage () { return window.location.href = "sorry2.html" ; } //--> </script> and then this: document.write ( '<form name="questionForm" action="javascript:checkAnswer()" method="post">' ) ; ... document.write ( '<input type="text" name="userAnswer" value="" size="90">' ) ; document.write ( '<INPUT TYPE="image" NAME="submit" SRC="stock/btn_send.gif" width="121" height="41" BORDER="0" ALT="submit">' ) ; document.write ( '\</p>' ) ; document.write ( '\</form>' ) ; I'm assuming there's something ugly in CheckAnswer from ./password.js . I can hack the form to bypass that javascript and go straight to the success page: document.write ( '<form name="questionForm" action="extra.html" method="post">' ) ; but I'd like to help my friend get his kids site working again. The CheckAnswer function is below. Is something going wrong in here? function checkAnswer () { currentAnswer = answersArray [ choiceNumber ] ; if (agt.indexOf("msie") != -1) { rawAnswer = document.questionForm.userAnswer.value ; } else { rawAnswer = document.callThis.document.questionForm.userAnswer.value ; } lcAnswer = rawAnswer.toLowerCase ( ) ; includedAnswer = lcAnswer.indexOf ( "currentAnswer" ) ; zadaAnswer = lcAnswer.indexOf ( "zada" ) ; brendanAnswer = lcAnswer.indexOf ( "brendan" ) ; nineAnswer = lcAnswer.indexOf ( "nine" ) ; thirtyAnswer = lcAnswer.indexOf ( "thirty" ) ; if ( choiceNumber == 0 ) { if ( includedAnswer == -1 && zadaAnswer == -1 && brendanAnswer == -1 ) { checked = "wrong" ; } } if ( choiceNumber == 8 ) { if ( includedAnswer == -1 && zadaAnswer == -1 && nineAnswer == -1 ) { checked = "wrong" ; } } if ( choiceNumber == 16 ) { if ( includedAnswer == -1 && zadaAnswer == -1 && thirtyAnswer == -1 ) { checked = "wrong" ; } } if ( choiceNumber != 0 && choiceNumber != 8 && choiceNumber != 16 ) { if ( includedAnswer == -1 && zadaAnswer == -1 ) { checked = "wrong" ; } } if ( checked == "wrong" ) { showWrongPage () ; } else { showRightPage () ; } } Thanks!

• The best JSF coding pattern for editing JPA entities using @RequestScoped only

  - by AlanObject

  I am in a project where I will write a lot of pages like this, so I want to use the most efficient (to write) coding pattern. Background: In the past I have used CODI's @ViewAccessScoped to preserve state between requests, and more recently I have started using flash scoped objects to save state. I can't use JSF @ViewScoped because I use CDI and they don't play well together. So I want to see if I can do this with only @RequestScoped backing beans. The page is designed like this (the p namespace is Primefaces): <f:metadata> <f:viewParam name="ID" value="#{backing.id}" /> </f:metadata> .... <h1>Edit Object Page</h1> <h:form id="formObj" rendered="#{backing.accessOK}"> <p:panelGrid columns="2"> <h:outputLabel value="Field #1:"/> <p:inputText value="#{backing.record.field1}" /> (more input fields) <h:outputLabel value="Action:" /> <h:panelGroup> <p:commandButton value="Save" action="#{backing.save}" /> <p:commandButton value="Cancel" action="backing.cancel" /> </h:panelGroup> </p:panelGrid> <p:messages showDetail="true" showSummary="true" /> </h:form> If the page is requested, the method accessOK() has the ability to keep the h:form from being rendered. Instead, the p:messages is shown with whatever FacesMessage(s) the accessOK() method cares to set. The pattern for the bean backing looks like this: @Named @RequestScoped public class Backing { private long id; private SomeJPAEntity record; private Boolean accessOK; public long getId() { return id; } public void setId(long value) { id = value; } public boolean accessOK() { if (accessOK != null) return accessOK; if (getRecord() == null) { // add a FacesMessage that explains the record // does not exist return accessOK = false; // note single = } // do any other access checks, such as write permissions return accessOK = true; } public SomeJPAEntity getRecord() { if (record != null) return record; if (getId() > 0) record = // get the record from DB else record = new SomeJPAEntity(); return record; } public String execute() { if (!accessOK()) return null; // bad edit // do other integrity checks here. If fail, set FacesMessages // and return null; if (getId() > 0) // merge the record back into the data base else // persist the record } } Here is what goes wrong with this model. When the Save button is clicked, a new instance of Backing is built, and then there are a lot of calls to the getRecord() getter before the setID() setter is called. So the logic in getRecord() breaks because it cannot rely on the id property being valid when it is called. When this was a @ViewAccessScoped (or ViewScoped) backing bean, then both the id and record properties are already set when the form is processed with the commandButton. Alternatively you can save those properties in flash storage but that has its own problems I want to avoid. So is there a way to make this programming model work within the specification?

• Rails: (Devise) Two different methods for new users?

  - by neezer

  I have a Rails 3 app with authentication setup using Devise with the registerable module enabled. I want to have new users who sign up using our outside register form to use the full Devise registerable module, which is happening now. However, I also want the admin user to be able to create new users directly, bypassing (I think) Devise's registerable module. With registerable disabled, my standard UsersController works as I want it to for the admin user, just like any other Rail scaffold. However, now new users can't register on their own. With registerable enabled, my standard UsersController is never called for the new user action (calling Devise::RegistrationsController instead), and my CRUD actions don't seem to work at all (I get dumped back onto my root page with no new user created and no flash message). Here's the log from the request: Started POST "/users" for 127.0.0.1 at 2010-12-20 11:49:31 -0500 Processing by Devise::RegistrationsController#create as HTML Parameters: {"utf8"=>"?", "authenticity_token"=>"18697r4syNNWHfMTkDCwcDYphjos+68rPFsaYKVjo8Y=", "user"=>{"email"=>"[email protected]", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "role"=>"manager"}, "commit"=>"Create User"} SQL (0.9ms) ... User Load (0.6ms) SELECT "users".* FROM "users" WHERE ("users"."id" = 2) LIMIT 1 SQL (0.9ms) ... Redirected to http://test-app.local/ Completed 302 Found in 192ms ... but I am able to register new users through the outside form. How can I get both of these methods to work together, such that my admin user can manually create new users and guest users can register on their own? I have my Users controller setup for standard CRUD: class UsersController < ApplicationController load_and_authorize_resource def index @users = User.where("id NOT IN (?)", current_user.id) # don't display the current user in the users list; go to account management to edit current user details end def new @user = User.new end def create @user = User.new(params[:user]) if @user.save flash[:notice] = "#{ @user.email } created." redirect_to users_path else render :action => 'new' end end def edit end def update params[:user].delete(:password) if params[:user][:password].blank? params[:user].delete(:password_confirmation) if params[:user][:password].blank? and params[:user][:password_confirmation].blank? if @user.update_attributes(params[:user]) flash[:notice] = "Successfully updated User." redirect_to users_path else render :action => 'edit' end end def delete end def destroy redirect_to users_path and return if params[:cancel] if @user.destroy flash[:notice] = "#{ @user.email } deleted." redirect_to users_path end end end And my routes setup as follows: TestApp::Application.routes.draw do devise_for :users devise_scope :user do get "/login", :to => "devise/sessions#new", :as => :new_user_session get "/logout", :to => "devise/sessions#destroy", :as => :destroy_user_session end resources :users do get :delete, :on => :member end authenticate :user do root :to => "application#index" end root :to => "devise/session#new" end

• Why doesn't the default model binder update my partial view model on postback?

  - by bdnewbe

  I have a class that contains another class as one of its properties. public class SiteProperties { public SiteProperties() { DropFontFamily = "Arial, Helvetica, Sans-serif"; } public string DropFontFamily { get; set; } private ResultPageProperties m_ResultPagePropertyList; public ResultPageProperties ResultPagePropertyList { get { if (m_ResultPagePropertyList == null) m_ResultPagePropertyList = new ResultPageProperties(); return m_ResultPagePropertyList; } set { m_ResultPagePropertyList = value; } } } The second class has just one property public class ResultPageProperties { public ResultPageProperties() { ResultFontFamily = "Arial, Helvetica, Sans-serif"; } public string ResultFontFamily { get; set; } } My controller just grabs the SiteProperties and returns the view. On submit, it accepts SiteProperties and returns the same view. public class CompanyController : Controller { public ActionResult SiteOptions(int id) { SiteProperties site = new SiteProperties(); PopulateProperyDropDownLists(); return View("SiteOptions", site); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult SiteOptions(SiteProperties properties) { PopulateProperyDropDownLists(); return View("SiteOptions", properties); } private void PopulateProperyDropDownLists() { var fontFamilyList = new List<SelectListItem>(); fontFamilyList.Add(new SelectListItem() { Text = "Arial, Helvetica, Sans-serif", Value = "Arial, Helvetica, Sans-serif" }); fontFamilyList.Add(new SelectListItem() { Text = "Times New Roman, Times, serif", Value = "Times New Roman, Times, serif" }); fontFamilyList.Add(new SelectListItem() { Text = "Courier New, Courier, Monospace", Value = "Courier New, Courier, Monospace" }); ViewData["FontFamilyList"] = fontFamilyList; } } The view contains a partial view that renders the ResultPageProperties Model. <% using (Html.BeginForm("SiteOptions", "Company", FormMethod.Post)) {%> <p><input type="submit" value="Submit" /></p> <div>View level input</div> <div> <label>Font family</label><br /> <%= Html.DropDownListFor(m => m.DropFontFamily, ViewData["FontFamilyList"] as List<SelectListItem>, new { Class = "UpdatesDropDownExample" })%> </div> <% Html.RenderPartial("ResultPagePropertyInput", Model.ResultPagePropertyList); %> <% } %> The partial is just <div style='margin-top: 1em;'>View level input</div> <div> <label>Font family</label><br /> <%= Html.DropDownListFor(m => m.ResultFontFamily, ViewData["FontFamilyList"] as List<SelectListItem>, new { Class = "UpdatesResultPageExample" })%> </div> OK, so when the page renders, you get "Arial, ..." in both selects. If you choose another option for both and click submit, the binder populates the SiteProperties object and passes it to the controller. However, the ResultFontFamily always contains the original value. I was expecting it to have the value the user selected. What am I missing?

• model binding of non-sequential arrays

  - by user281180

  I am having a table in which i`m dynamically creating and deleting rows. How can I change the code such that the rows be added and deleted and the model info property filled accordingly. Bearing in mind that the rows can be dynamically created and deleted, I may have Info[0], Inf0[3], info[4]... My objective is to be able to bind the array even if it`s not in sequence. Model public class Person { public int[] Size { get; set; } public string[] Name { get; set; } public Info[]info { get; set; } } public class Info { public string Address { get; set; } public string Tel { get; set; } View <script type="text/javascript" language="javascript"> $(function () { var count = 1; $('#AddSize').live('click', function () { $("#divSize").append('</br><input type="text" id="Size" name="Size" value=""/><input type = "button" id="AddSize" value="Add"/>'); }); $('#AddName').live('click', function () { $("#divName").append('</br><input type="text" id="Name" name="Name" value=""/><input type = "button" id="AddName" value="Add"/>'); }); $('#AddRow').live('click', function () { $('#details').append('<tr><td>Address</td><td> <input type="text" name="Info[' + count + '].Address"/></td><td>Tel</td><td><input type="text" name="Info[' + count++ + '].Tel"/></td> <td><input type="button" id="AddRow" value="Add"/> </td></tr>'); }); }); </script> </head> <body> <form id="closeForm" action="<%=Url.Action("Create",new{Action="Create"}) %>" method="post" enctype="multipart/form-data"> <div id="divSize"> <input type="text" name="Size" value=""/> <input type="button" value="Add" id="AddSize" /> </div> <div id="divName"> <input type="text" name="Name" value=""/> <input type="button" value="Add" id="AddName" /> </div> <div id="Tab"> <table id="details"> <tr><td>Address</td><td> <input type="text" name="Info[0].Address"/></td><td>Tel</td><td><input type="text" name="Info[0].Tel"/></td> <td><input type="button" id="AddRow" value="Add"/> </td></tr> </table> </div> <input type="submit" value="Submit" /> </form> </body> } Controller public ActionResult Create(Person person) { return new EmptyResult(); }

• DropDownList not working 100% in ASP.Net MVC

  - by Program.X

  I am quite confused with how to effectively use the Html.DropDownList helper for ASP.NET MVC. Background: I have a 5-page form, which saves data to the form each time "Next" is clicked. Users may navigate back and forth between sections, so previous sections will already be pre-populated with previously-entered data. This works for TextBoxes. But not DropDownLists. I have tried a load of different methods, including: http://stackoverflow.com/questions/867117/how-to-add-static-list-of-items-in-mvc-html-dropdownlist/867218#867218 http://stackoverflow.com/questions/2080802/setting-selected-item-to-dropdownlist-in-mvc-application I have a ViewModel such taht I have got my lists and my Model (a LINQ-to-SQL generated class) as properties. eg: public class ConsultantRegistrationFormViewModel { public IConsultantRegistration ConsultantRegistration { get; private set; } public SelectList Titles { get; private set; } public SelectList Countries { get; private set; } public SelectList Currencies { get; private set; } public int CurrentSection { get; private set; } private ConsultantRegistrationFormViewModel(IConsultantRegistration consultantRegistration) { ConsultantRegistration = consultantRegistration; CurrentSection = 1; Titles = new SelectList(new string[] { "Mr", "Mrs", "Miss", "Ms", "Dr", "Sir" }); Countries = new SelectList(countries.Select(q => q.Name)); Currencies = new SelectList(currencies,"CurrencyCode","FriendlyForm"); } } My Controller's Edit Action on GET looks like: public class ConsultantRegistrationController : Controller { public IConsultantRegistrationRepository ConsultantRegistrationRepository { get; private set; } public ICountryRepository CountryRepository { get; private set; } public IEnumerable<ICountry> Countries { get; private set; } public ConsultantRegistrationController() { ConsultantRegistrationRepository = RepositoryFactory.CreateConsultantRegistrationRepository(); CountryRepository = RepositoryFactory.CreateCountryRepository(); Countries = CountryRepository.GetCountries().ToArray(); } public ActionResult Edit(Guid id, int sectionIndex) { IConsultantRegistration consultantRegistration = ConsultantRegistrationRepository.GetConsultantRegistration(id); SelectList bankBranchCountriesSelectList = new SelectList(Countries, "BankBranchCountry", "CountryName", consultantRegistration.BankBranchCountry); ViewData["bankBranchCountrySelectList"] = bankBranchCountriesSelectList; return View(new ConsultantRegistrationFormViewModel(consultantRegistration,sectionIndex, Countries,Currencies)); } } With my View doing: <%: Html.DropDownList("ConsultantRegistration.BankBranchCountry",ViewData["bankBranchCountrySelectList"] as SelectList) %> This gives me the error: DataBinding: 'IWW.ArrowPay.ConsultantRegistration.Data.Country' does not contain a property with the name 'BankBranchCountry'. Which it does, have a look at the schema of this property: public interface IConsultantRegistration { Guid ID { get; set; } [DisplayName("Branch Country")] string BankBranchCountry { get; set; } } (My LINQ-to-SQL type ConsultantRegistration implemented IConsultantRegistration) It seems that it is trying to bind to the wrong type, though? If I use this in my view (and use my Controller's Countries property): <%: Html.DropDownList("ConsultantRegistration.BankBranchCountry ",Model.Countries,"(select a Country)") %> I get the saved value fine, but my model doesn't update on POST. And if I use this in my view: <%: Html.DropDownListFor(model=>model.ConsultantRegistration.BankBranchCountry ",Model.Countries,"(select a Country)") %> I get the list, and it POSTs the selected value back, but does not pre-select the currently selected item in my model on the view. So I have a bit of the solution all over the place, but not all in one place. Hope you can help fill in my ignorance.
