• Forms Authentication works on dev server but not production server (same SQL db)

  - by Desmond

  Hi, I have the same problem as a previously solved question however, this solution did not help me. I have posted the previous question and answer below: http://stackoverflow.com/questions/2215963/forms-authentication-works-on-dev-server-but-not-production-server-same-sql-db/2963985#2963985 Question: I've never had this problem before, I'm at a total loss. I have a SQL Server 2008 database with ASP.NET Forms Authentication, profiles and roles created and is functional on the development workstation. I can login using the created users without problem. I back up the database on the development computer and restore it on the production server. I xcopy the DLLs and ASP.NET files to the server. I make the necessary changes in the web.config, changing the SQL connection strings to point to the production server database and upload it. I've made sure to generate a machine key and it is the same on both the development web.config and the production web.config. And yet, when I try to login on the production server, the same user that I'm able to login successfully with on the development computer, fails on the production server. There is other content in the database, the schema generated by FluentNHibernate. This content is able to be queried successfully on both development and production servers. This is mind boggling, I believe I've verified everything, but obviously it is still not working and I must have missed something. Please, any ideas? Answer: I ran into a problem with similar symptoms at one point by forgetting to set the applicationName attribute in the web.config under the membership providers element. Users are associated to a specific application. Since I didn't set the applicationName, it defaulted to the application path (something like "/MyApplication"). When it was moved to production, the path changed (for example to "/WebSiteFolder/SomeSubFolder /MyApplication"), so the application name defaulted to the new production path and an association could not be made to the original user accounts that were set up in development. Could your issues possibly be the same as mine? I have this already in my web.config but still get the issue. Any ideas? <membership> <providers> <clear/> <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" applicationName="/"/> </providers> </membership> <profile> <providers> <clear/> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" applicationName="/"/> </providers> </profile> <roleManager enabled="false"> <providers> <clear/> <add connectionStringName="ApplicationServices" applicationName="/" name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> <add applicationName="/" name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> </providers> </roleManager> Any help is greatly appriciated.

• UIButtons in UIScrollView stop it scrolling, how to fix?

  - by Mark McFarlane

  Hi all, I have a problem with adding a set of UIButtons to a UIScrollView. With the buttons added it seems that the scroll command is not being passed to the scroll view as the buttons cover the whole surface. I've read various posts on this but still can't figure it out. I'm pretty new to iPhone programming so there's probably something obvious I've missed. I've tried things like canCancelContentTouches and delaysContentTouches to TRUE and FALSE. Here is the code I use to add the buttons to the scrollview. The scrollview was created in IB and is passed in to the function: -(void)drawCharacters:(NSMutableArray *)chars:(UIScrollView *)target_view { //NSLog(@"CLEARING PREVIOUS BUTTONS"); //clear previous buttons for parts/kanji if(target_view == viewParts){ for (UIButton *btn in parts_buttons) { [btn removeFromSuperview]; } [parts_buttons removeAllObjects]; } else if(target_view == viewKanji){ for (UIButton *btn in kanji_buttons) { [btn removeFromSuperview]; } [kanji_buttons removeAllObjects]; } //display options int chars_per_line = 9; //change this to change the number of chars displayed on each line if(target_view == viewKanji){ chars_per_line = 8; } int char_gap = 0; //change this to change the margin between chars int char_dimensions = (320/chars_per_line)-(char_gap*2); //set starting x, y coords int x = 0, y = 0; //increment y coord y += char_gap; //NSLog(@"ABOUT TO DRAW FIRST BUTTON"); for(NSMutableArray *char_arr in chars){ //increment x coord x += char_gap; //draw at x and y UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom]; myButton.frame = CGRectMake(x, y, char_dimensions, char_dimensions); // position in the parent view and set the size of the button [myButton setTitle:[char_arr objectAtIndex:0] forState:UIControlStateNormal]; [myButton setTitleColor:[UIColor darkGrayColor] forState:UIControlStateNormal]; [myButton setTitleColor:[UIColor colorWithRed:0.8 green:0.8 blue:0.8 alpha:1.0] forState:UIControlStateDisabled]; myButton.titleLabel.font = [UIFont boldSystemFontOfSize:22]; if(target_view == viewKanji){ myButton.titleLabel.font = [UIFont boldSystemFontOfSize:30]; } // add targets and actions if(target_view == viewParts){ [myButton addTarget:self action:@selector(partSelected:) forControlEvents:UIControlEventTouchUpInside]; } else if(target_view == viewKanji){ [myButton addTarget:self action:@selector(kanjiSelected:) forControlEvents:UIControlEventTouchUpInside]; [myButton setTag:(int)[char_arr objectAtIndex:1]]; } //if the part isnt in the current list of kanji, disable and dim it if(target_view == viewParts){ if([kanji count] > 0){ [myButton setEnabled:NO]; } bool do_break = NO; for(NSMutableArray *arr in kanji){ //NSLog([NSString stringWithFormat:@"CHECKING PARTS AGAINST %d KANJI", [kanji count]]); for(NSString *str in [[arr objectAtIndex:2] componentsSeparatedByString:@" "]){ if(([myButton.titleLabel.text isEqualToString:str])){ //NSLog(@"--------------MATCH!!!-----------------"); [myButton setEnabled:YES]; for(NSString *str1 in parts_selected){ if(([myButton.titleLabel.text isEqualToString:str1])){ [myButton setEnabled:NO]; break; } } do_break = YES; break; } if(do_break) break; } if(do_break) break; } } // add to a view [target_view addSubview:myButton]; //update coords of next button x += char_dimensions+ char_gap; if (x > (320-char_dimensions)) { x = 0; y += char_dimensions + (char_gap*2); } //add button to global array to be removed from view next update if(target_view == viewParts){ [parts_buttons addObject:myButton]; } else if(target_view == viewKanji){ [kanji_buttons addObject:myButton]; } } //NSLog(@"FINISHED DRAWING ALL BUTTONS"); } Any help on this would be greatly appreciated. I just need to fix this to finish my app.

  hi, everything is working fine with my jqgrid except a small issue. i have defined postData below: $(document).ready(function() { $("#ctl00_ContentPlaceHolder2_drpUSite").change(function() { site = ($("#ctl00_ContentPlaceHolder2_drpUSite").val()); loadusergrid(); }); var usrparams = new Object(); var site = ($("#ctl00_ContentPlaceHolder2_drpUSite").val()); //----grid code--------- $("#users").jqGrid({ prmNames: { _search: "isSearch", nd: null, rows: "numRows", page: "page", sort: "sortField", order: "sortOrder" }, // add by default to avoid webmethod parameter conflicts postData: { searchString: '', searchField: '', searchOper: '', sites: site }, datatype: function(postdata) { mtype: "GET", $.ajax({ url: 'Users.aspx/GetUsers', type: "POST", contentType: "application/json; charset=utf-8", data: JSON.stringify(postdata), dataType: "json", success: function(data, st) { if (st == "success") { var grid = $("#users")[0]; var m = JSON.parse(data.d); grid.addJSONData(m); } }, error: function() { alert("Loading Failed!"); } }); }, // this is what jqGrid is looking for in json callback jsonReader: { root: "rows", page: "page", total: "total", records: "records", cell: "cell", id: "login", repeatitems: true }, colNames: ['Login', 'First Name', 'Last Name', 'Email', 'Site', 'Role', 'Room', 'UnitID', 'Supervisor', 'Super'], colModel: [ { name: 'login', index: 'login', width: 20 }, { name: 'fname', index: 'fname', width: 20, hidden: true }, { name: 'lname', index: 'lname', width: 60, align: "center", sortable: true, searchoptions: { sopt: ['eq', 'ne']} }, { name: 'email', index: 'email', width: 20, align: "center", sortable: false }, { name: 'site', index: 'site', width: 50, align: "center", sortable: true, searchoptions: { sopt: ['eq', 'ne']} }, { name: 'role', index: 'role', width: 15, align: "center", sortable: true, searchoptions: { sopt: ['eq', 'ne']} }, { name: 'room', index: 'room', width: 30, align: "center", sortable: true }, { name: 'unitid', index: 'unitid', width: 10, align: "center", sortable: false }, { name: 'super', index: 'super', width: 20 }, { name: 'supername', index: 'supername', width: 10, align: "center", sortable: false }, ], pager: "#pageusers", viewrecords: true, caption: "Registered Users", imgpath: 'themes/steel/images', rowNum: 20, rowList: [10, 20, 30, 40, 50], sortname: "pname", sortorder: "desc", showpage: true, gridModel: true, gridToolbar: true, onSelectRow: function(id) { var ret = jQuery("#users").getRowData(id); accpara.id = ret.id; accpara.pname = ret.pname; accpara.pid = ret.pid; accpara.bld = ret.bld; accpara.cname = ret.cname; accpara.amt = ret.amt; accpara.status = ret.status; accpara.notes = ret.notes; accpara.lname = ret.lname; } }); jQuery("#users").navGrid('#pageusers', { view: false, del: false, add: false, edit: false }, {}, // default settings for edit {}, // default settings for add {}, // delete {closeOnEscape: true, multipleSearch: true, closeAfterSearch: true }, // search options {} ); $("#users").setGridWidth(1300, true); $("#users").setGridHeight(500, true); jQuery("#users").jqGrid('filterToolbar'); //----grid code ends here function loadusergrid() { $("#users").setGridParam({ page: 1 }, { pgbuttons: true }, { pginput: true }, { postData: { "site": site} }).trigger("reloadGrid"); } }); when page loads for the 1st time, this works.. now i have 4 drop-downs which filter users. i have written a function which reloads the grid when the dropdown is changed, but it isnt working.. what am i doing wrong here?? when i enable postback for the dropdowns, i get the filtered result. i want to avoid postbacks on my page :). right now i have added just the site dropdown as the filter. once this starts working ill add the remaining 3. firebug shows the ajax call is fired successfully but with an empty sitename. please note that the site dropdown cntains an empty value when page is loaded for the 1st time. thanks in advance

• Feedback on TOC Generation Code

  - by vikramjb

  Hi All I wrote a small code to generate ToC or Hierachical Bullets like one sees in a word document. Like the following set 1. 2 3 3.1 3.1.1 4 5 and so on so forth, the code is working but I am not happy with the code I have written, I would appreciate if you guys could shed some light on how I can improve my C# code.

• Marking multi-level nested forms as "dirty" in Rails

  - by Charles Kihe

  I have a three-level multi-nested form in Rails. The setup is like this: Projects have many Milestones, and Milestones have many Notes. The goal is to have everything editable within the page with JavaScript, where we can add multiple new Milestones to a Project within the page, and add new Notes to new and existing Milestones. Everything works as expected, except that when I add new notes to an existing Milestone (new Milestones work fine when adding notes to them), the new notes won't save unless I edit any of the fields that actually belong to the Milestone to mark the form "dirty"/edited. Is there a way to flag the Milestone so that the new Notes that have been added will save? Edit: sorry, it's hard to paste in all of the code because there's so many parts, but here goes: Models class Project < ActiveRecord::Base has_many :notes, :dependent => :destroy has_many :milestones, :dependent => :destroy accepts_nested_attributes_for :milestones, :allow_destroy => true accepts_nested_attributes_for :notes, :allow_destroy => true, :reject_if => proc { |attributes| attributes['content'].blank? } end class Milestone < ActiveRecord::Base belongs_to :project has_many :notes, :dependent => :destroy accepts_nested_attributes_for :notes, :allow_destroy => true, :allow_destroy => true, :reject_if => proc { |attributes| attributes['content'].blank? } end class Note < ActiveRecord::Base belongs_to :milestone belongs_to :project scope :newest, lambda { |*args| order('created_at DESC').limit(*args.first || 3) } end I'm using an jQuery-based, unobtrusive version of Ryan Bates' combo helper/JS code to get this done. Application Helper def add_fields_for_association(f, association, partial) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(partial, :f => builder) end end I render the form for the association in a hidden div, and then use the following JavaScript to find it and add it as needed. JavaScript function addFields(link, association, content, func) { var newID = new Date().getTime(); var regexp = new RegExp("new_" + association, "g"); var form = content.replace(regexp, newID); var link = $(link).parent().next().before(form).prev(); if (func) { func.call(); } return link; } I'm guessing the only other relevant piece of code that I can think of would be the create method in the NotesController: def create respond_with(@note = @owner.notes.create(params[:note])) do |format| format.js { render :json => @owner.notes.newest(3).all.to_json } format.html { redirect_to((@milestone ? [@project, @milestone, @note] : [@project, @note]), :notice => 'Note was successfully created.') } end end The @owner ivar is created in the following before filter: def load_milestone @milestone = @project.milestones.find(params[:milestone_id]) if params[:milestone_id] end def determine_owner @owner = load_milestone @owner ||= @project end Thing is, all this seems to work fine, except when I'm adding new notes to existing milestones. The milestone has to be "touched" in order for new notes to save, or else Rails won't pay attention.

• TableViewCell autorelease error

  - by iAm

  OK, for two days now i have been trying to solve an error i have inside the cellForRowAtIndex method, let start by saying that i have tracked down the bug to this method, the error is [CFDictionary image] or [Not a Type image] message sent to deallocated instance. I know about the debug flags, NSZombie, MallocStack, and others, they helped me narrow it down to this method and why, but I do not know how to solve besides a redesign of the app UI. SO what am i trying to do, well for this block of code, displays a purchase detail, which contains items, the items are in there own section, now when in edit mode, there appears a cell at the bottom of the items section with a label of "Add new Item", and this button will present a modal view of the add item controller, item is added and the view returns to the purchase detail screen, with the just added item in the section just above the "add new Item" cell, the problem happens when i scroll the item section off screen and back into view the app crashes with EXC_BAD_ACCESS, or even if i don't scroll and instead hit the back button on the navBar, still the same error. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = nil; switch (indexPath.section) { case PURCHASE_SECTION: { static NSString *cellID = @"GenericCell"; cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:cellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } switch (indexPath.row) { case CATEGORY_ROW: cell.textLabel.text = @"Category:"; cell.detailTextLabel.text = [self.purchase.category valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case TYPE_ROW: cell.textLabel.text = @"Type:"; cell.detailTextLabel.text = [self.purchase.type valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case VENDOR_ROW: cell.textLabel.text = @"Payment:"; cell.detailTextLabel.text = [self.purchase.vendor valueForKey:@"name"]; cell.accessoryType = UITableViewCellAccessoryNone; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; break; case NOTES_ROW: cell.textLabel.text = @"Notes"; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; default: break; } break; } case ITEMS_SECTION: { NSUInteger itemsCount = [items count]; if (indexPath.row < itemsCount) { static NSString *itemsCellID = @"ItemsCell"; cell = [tableView dequeueReusableCellWithIdentifier:itemsCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:itemsCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } singleItem = [self.items objectAtIndex:indexPath.row]; cell.textLabel.text = singleItem.name; cell.detailTextLabel.text = [singleItem.amount formattedDataDisplay]; cell.imageView.image = [singleItem.image image]; } else { static NSString *AddItemCellID = @"AddItemCell"; cell = [tableView dequeueReusableCellWithIdentifier:AddItemCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:AddItemCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } cell.textLabel.text = @"Add Item"; } break; } case LOCATION_SECTION: { static NSString *localID = @"LocationCell"; cell = [tableView dequeueReusableCellWithIdentifier:localID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:localID] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; } cell.textLabel.text = @"Purchase Location"; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.editingAccessoryType = UITableViewCellAccessoryNone; break; } default: break; } return cell; } the singleItem is of Modal Type PurchaseItem for core data now that i know what is causing the error, how do i solve it, I have tried everything that i know and some of what i dont know but still, no progress, please any suggestions as to how to solve this without redesign is my goal, perhaps there is an error i am doing that I cannot see, but if it's the nature of autorelease, than i will redesign.

• Placing component on Glass Pane

  - by Chris Lieb

  I have a subclass of JLabel that forms a component of my GUI. I have implemented the ability to drag and drop the component from one container to another, but without any visual effects. I want to have this JLabel follow the cursor during the drag of the item from one container to another. I figured that I could just create a glass pane and draw it on there. However, even after I add the component to the glass pane, set the component visible, and set the glass pane visible, and set the glass pane as opaque, I still so not see the component. I know the component works because I can add it to the content pane and have it show up. How do I add a component to the glass pane? package wpics509s10t7.view; import javax.swing.*; import wpics509s10t7.model.Tile; import java.awt.*; import java.awt.dnd.DragSource; import java.awt.event.AWTEventListener; import java.awt.event.MouseEvent; /** * GlassPane tutorial * "A well-behaved GlassPane" * http://weblogs.java.net/blog/alexfromsun/ * <p/> * This is the final version of the GlassPane * it is transparent for MouseEvents, * and respects underneath component's cursors by default, * it is also friedly for other users, * if someone adds a mouseListener to this GlassPane * or set a new cursor it will respect them * * @author Alexander Potochkin */ public class GlassPane extends JPanel implements AWTEventListener { private static final long serialVersionUID = 1L; private final JFrame frame; private TileView tv; // subclass of JLabel private Point point; private WordStealApp wsa; public GlassPane(JFrame frame, WordStealApp wsa) { super(null); this.wsa = wsa; this.frame = frame; setOpaque(true); setLayout(null); setVisible(true); composite = AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.5f); } public void beginDrag(Tile t, Point p) { this.tv = new TileView(t, null, this.wsa, true); this.add(this.tv); System.out.println("Starting point: x=" + p.getX() + ",y=" + p.getY()); this.tv.setLocation((int)p.getX(), (int)p.getY()); this.tv.setVisible(true); } public void endDrag(Point p) { System.out.println("Ending point: x=" + p.getX() + ",y=" + p.getY()); this.remove(this.tv); this.tv.setVisible(false); this.tv = null; } public void eventDispatched(AWTEvent event) { if (event instanceof MouseEvent) { MouseEvent me = (MouseEvent) event; if (!SwingUtilities.isDescendingFrom(me.getComponent(), frame)) { return; } if (me.getID() == MouseEvent.MOUSE_EXITED && me.getComponent() == frame) { if (tv != null) { tv.setVisible(false); } point = null; } else { MouseEvent converted = SwingUtilities.convertMouseEvent(me.getComponent(), me, frame.getGlassPane()); point = converted.getPoint(); } repaint(); } } /** * If someone adds a mouseListener to the GlassPane or set a new cursor * we expect that he knows what he is doing * and return the super.contains(x, y) * otherwise we return false to respect the cursors * for the underneath components */ @Override public boolean contains(int x, int y) { if (getMouseListeners().length == 0 && getMouseMotionListeners().length == 0 && getMouseWheelListeners().length == 0 && getCursor() == Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR)) { return false; } return super.contains(x, y); } }

• Zend_Nav in zend framework issue getting menu to show up

  - by Kalle Johansson

  Hi ! First time of here, so please bare with me. I have to following problem, using zend framework, specifically zend_nav to create a reusable menu to be passed in via the layout/layout.phtml page. These are the code fragments in their respective files. first of in application/configs/navigation.xml, <configdata> <nav> <label>Home</label> <controller>index</controller> <action>index</action> <pages> <add> <label>Add</label> <controller>post</controller> <action>add</action> </add> <login> <label>Admin</label> <controller>login</controller> <action>login</action> </login> </pages> </nav> </configdata> this is then passed into an object in the Bootstrap.php file(only showing that specific method) protected function __initNavigation(){ $this->bootstrap('layout'); $layout = $this->getResource('layout'); $view = $layout->getView(); $config = new Zend_Config_Xml(APPLICATION .'/config/navigation.xml', 'nav'); $container = new Zend_Navigation($config); $view->navigation($container); } and then finally in the view layout.phtml, the object should return the menu <!-- application/layouts/scripts/layout.phtml --> <?php echo $this->doctype() ?> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Zend Blog !</title> <?php echo $this->headLink()->appendStylesheet('/css/global.css')?> </head> <body> <div id="header"> <div id="header-logo"> <b>Blog Me !</b> </div> </div> <div id="menu"> <?php echo $this->navigation()->menu() ?> </div> <div id="content"> <?php echo $this->layout()->content ?> </div> </body> </html> The menu does however not show up when i start up my app in the browser, any ideas as to might have gone wrong, is humbly received. Thanks in advance Kalle Johansson

• Preventing multiple repeat selection of synchronized Controls ?

  - by BillW

  The working code sample here synchronizes (single) selection in a TreeView, ListView, and ComboBox via the use of lambda expressions in a dictionary where the Key in the dictionary is a Control, and the Value of each Key is an Action<int. Where I am stuck is that I am getting multiple repetitions of execution of the code that sets the selection in the various controls in a way that's unexpected : it's not recursing : there's no StackOverFlow error happening; but, I would like to figure out why the current strategy for preventing multiple selection of the same controls is not working. Perhaps the real problem here is distinguishing between a selection update triggered by the end-user and a selection update triggered by the code that synchronizes the other controls ? Note: I've been experimenting with using Delegates, and forms of Delegates like Action<T>, to insert executable code in Dictionaries : I "learn best" by posing programming "challenges" to myself, and implementing them, as well as studying, at the same time, the "golden words" of luminaries like Skeet, McDonald, Liberty, Troelsen, Sells, Richter. Note: Appended to this question/code, for "deep background," is a statement of how I used to do things in pre C#3.0 days where it seemed like I did need to use explicit measures to prevent recursion when synchronizing selection. Code : Assume a WinForms standard TreeView, ListView, ComboBox, all with the same identical set of entries (i.e., the TreeView has only root nodes; the ListView, in Details View, has one Column). private Dictionary<Control, Action<int>> ControlToAction = new Dictionary<Control, Action<int>>(); private void Form1_Load(object sender, EventArgs e) { // add the Controls to be synchronized to the Dictionary // with appropriate Action<int> lambda expressions ControlToAction.Add(treeView1, (i => { treeView1.SelectedNode = treeView1.Nodes[i]; })); ControlToAction.Add(listView1, (i => { listView1.Items[i].Selected = true; })); ControlToAction.Add(comboBox1, (i => { comboBox1.SelectedIndex = i; })); } private void synchronizeSelection(int i, Control currentControl) { foreach(Control theControl in ControlToAction.Keys) { // skip the 'current control' if (theControl == currentControl) continue; // for debugging only Console.WriteLine(theControl.Name + " synchronized"); // execute the Action<int> associated with the Control ControlToAction[theControl](i); } } private void treeView1_AfterSelect(object sender, TreeViewEventArgs e) { synchronizeSelection(e.Node.Index, treeView1); } private void listView1_SelectedIndexChanged(object sender, EventArgs e) { // weed out ListView SelectedIndexChanged firing // with SelectedIndices having a Count of #0 if (listView1.SelectedIndices.Count > 0) { synchronizeSelection(listView1.SelectedIndices[0], listView1); } } private void comboBox1_SelectedValueChanged(object sender, EventArgs e) { if (comboBox1.SelectedIndex > -1) { synchronizeSelection(comboBox1.SelectedIndex, comboBox1); } } background : pre C# 3.0 Seems like, back in pre C# 3.0 days, I was always using a boolean flag to prevent recursion when multiple controls were updated. For example, I'd typically have code like this for synchronizing a TreeView and ListView : assuming each Item in the ListView was synchronized with a root-level node of the TreeView via a common index : // assume ListView is in 'Details View,' has a single column, // MultiSelect = false // FullRowSelect = true // HideSelection = false; // assume TreeView // HideSelection = false // FullRowSelect = true // form scoped variable private bool dontRecurse = false; private void treeView1_AfterSelect(object sender, TreeViewEventArgs e) { if(dontRecurse) return; dontRecurse = true; listView1.Items[e.Node.Index].Selected = true; dontRecurse = false; } private void listView1_SelectedIndexChanged(object sender, EventArgs e) { if(dontRecurse) return // weed out ListView SelectedIndexChanged firing // with SelectedIndices having a Count of #0 if (listView1.SelectedIndices.Count > 0) { dontRecurse = true; treeView1.SelectedNode = treeView1.Nodes[listView1.SelectedIndices[0]]; dontRecurse = false; } } Then it seems, somewhere around FrameWork 3~3.5, I could get rid of the code to suppress recursion, and there was was no recursion (at least not when synchronizing a TreeView and a ListView). By that time it had become a "habit" to use a boolean flag to prevent recursion, and that may have had to do with using a certain third party control.

In other words, without adding x:Class to the top of Generic.xaml and thus creating a code-behind file for it, which I assume you wouldn't want to do, how do you handle events for elements in your xaml that don't have a Command property (which is just about everything other than a Button)? Should LooklessControl have it's own XAML file (much like what you get when you create a new UserControl) associated with it that Generic.xaml just pulls in as a MergedDictionar as its default template? Or is there some other acknowledged way to do what I'm trying to do?

• C# Windows Service XML

  - by Goober

  Scenario I have a windows service written in C# that performs some processing based on parsing an XML file and use that data to carry out various tasks. The service also does various bits of logging - which uses settings from an APP.Config file. The Problem When the service is compiled, installed and run, the XML file seems to disappear. I'm getting the impression that it is just ignored or something like that. So far I've tried using TWO App.Config files, one named App.Config that contains settings for the service, and the other called MyService.exe.config that contains all of the data that was used in the XML file (the idea being that I can parse the XML from a config file that actually gets compiled and appears in my installation directory. However When I do this, all that happens is that ONE config file appears (with the name MyService.exe.config), but it contains the contents of the App.Config file and not the XML data that I want to parse. What I need All I want is to have a config file for my settings, and an XML file for my data. Question Is this possible? I know the application works as it was originally built as a console application that ran fine. Other The application has to be designed this way (as in, I need my data stored as XML, and my settings stored in a config file). Thoughts If I could somehow combine the contents of the two files into ONE config file, that would be one way of solving the problem. However, I have tried this and of course I get a "Type Initialisation Exception", as the config file cannot interprate the XML data (probably because the tags are custom and do not form any part of the config schema - or something like that). Ideas Please could someone explain to me if it is possible for me to have an XML file AND a config file that will actually be compiled and stored in my installation directory for the service when it is run? CODE Custom XML/Data Config File <?xml version="1.0" encoding="utf-8" ?> <configuration> <servers> <SV066930> <add name="Name" value = "SV066930" /> <processes> <SimonTest1> <add name="ProcessName" value="notepad.exe" /> <add name="CommandLine" value="C:\\WINDOWS\\system32\\notepad.exe C:\\WINDOWS\\Profiles\\TA2TOF1\\Desktop\\SimonTest1.txt" /> </SimonTest1> </processes> </SV066930> </servers> </configuration> APP.Config Settings File <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxx" /> </configSections> <connectionStrings> <add name="DB" connectionString="Data Source=etc......" /> </connectionStrings> </configuration> Help greatly appreciated.

• drupal_get_form is not passing along node array

  - by ElectronicBlacksmith

  I have not been able to get drupal_get_form to pass on the node data. Code snippets are below. The drupal_get_form documentation (api.drupal.org) states that it will pass on the extra parameters. I am basing the node data not being passed because (apparently) $node['language'] is not defined in hook_form which causes $form['qqq'] not to be created and thus the preview button shows up. My goal here is that the preview button show up using path "node/add/author" but doesn't show up for "milan/author/add". Any alternative methods for achieving this goal would be helpful but the question I want answered is in the preceding paragraph. Everything I've read indicates that it should work. This menu item $items['milan/author/add'] = array( 'title' = 'Add Author', 'page callback' = 'get_author_form', 'access arguments' = array('access content'), 'file' = 'author.pages.inc', ); calls this code function get_author_form() { //return node_form(NULL,NULL); //return drupal_get_form('author_form'); return author_ajax_form('author'); } function author_ajax_form($type) { global $user; module_load_include('inc', 'node', 'node.pages'); $types = node_get_types(); $type = isset($type) ? str_replace('-', '_', $type) : NULL; // If a node type has been specified, validate its existence. if (isset($types[$type]) && node_access('create', $type)) { // Initialize settings: $node = array('uid' = $user-uid, 'name' = (isset($user-name) ? $user-name : ''), 'type' = $type, 'language' = 'bbb','bbb' = 'TRUE'); $output = drupal_get_form($type .'_node_form', $node); } return $output; } And here is the hook_form and hook_form_alter code function author_form_author_node_form_alter(&$form, &$form_state) { $form['author']=NULL; $form['taxonomy']=NULL; $form['options']=NULL; $form['menu']=NULL; $form['comment_settings']=NULL; $form['files']=NULL; $form['revision_information']=NULL; $form['attachments']=NULL; if($form["qqq"]) { $form['buttons']['preview']=NULL; } } function author_form(&$node) { return make_author_form(&$node); } function make_author_form(&$node) { global $user; $type = node_get_types('type', $node); $node = author_make_title($node); drupal_set_breadcrumb(array(l(t('Home'), NULL), l(t($node-title), 'node/' . $node-nid))); $form['authorset'] = array( '#type' = 'fieldset', '#title' = t('Author'), '#weight' = -50, '#collapsible' = FALSE, '#collapsed' = FALSE, ); $form['author_id'] = array( '#access' = user_access('create pd_recluse entries'), '#type' = 'hidden', '#default_value' = $node-author_id, '#weight' = -20 ); $form['authorset']['last_name'] = array( '#type' = 'textfield', '#title' = t('Last Name'), '#maxlength' = 60, '#default_value' = $node-last_name ); $form['authorset']['first_name'] = array( '#type' = 'textfield', '#title' = t('First Name'), '#maxlength' = 60, '#default_value' = $node-first_name ); $form['authorset']['middle_name'] = array( '#type' = 'textfield', '#title' = t('Middle Name'), '#maxlength' = 60, '#default_value' = $node-middle_name ); $form['authorset']['suffix_name'] = array( '#type' = 'textfield', '#title' = t('Suffix Name'), '#maxlength' = 14, '#default_value' = $node-suffix_name ); $form['authorset']['body_filter']['body'] = array( '#access' = user_access('create pd_recluse entries'), '#type' = 'textarea', '#title' = 'Describe Author', '#default_value' = $node-body, '#required' = FALSE, '#weight' = -19 ); $form['status'] = array( '#type' = 'hidden', '#default_value' = '1' ); $form['promote'] = array( '#type' = 'hidden', '#default_value' = '1' ); $form['name'] = array( '#type' = 'hidden', '#default_value' = $user-name ); $form['format'] = array( '#type' = 'hidden', '#default_value' = '1' ); // NOTE in node_example there is some addition code here not needed for this simple node-type $thepath='milan/author'; if($_REQUEST["theletter"]) { $thepath .= "/" . $_REQUEST["theletter"]; } if($node['language']) { $thepath='milan/authorajaxclose'; $form['qqq'] = array( '#type' = 'hidden', '#default_value' = '1' ); } $form['#redirect'] = $thepath; return $form; } That menu path coincides with this theme (PHPTemplate)

• datatables-multi-filter-select

  - by user1871603

  I am using the jquery plug-in datatables. I am using the feature, datatables-multi-filter-select on my website with php code. I want to move the drop down filter from the footer to the header like in the following example: http://www.datatables.net/extras/thirdparty/ColumnFilterWidgets/DataTables/extras/ColumnFilterWidgets/ Can anyone please update the following PHP code sample to accomplish this? Code: /** * Register necessary Plugin Filters */add_filter( 'tablepress_shortcode_table_default_shortcode_atts', 'tablepress_add_shortcode_parameters_multi_filter_select' );add_filter( 'tablepress_table_render_options', 'tablepress_set_table_foot_option', 10, 2 );add_filter( 'tablepress_table_js_options', 'tablepress_add_multi_filter_select_js_options', 10, 3 );add_filter( 'tablepress_datatables_command', 'tablepress_add_multi_filter_select_js_command', 10, 5 ); /** * Add "datatables_multi_filter_select" as a valid parameter to the [table /] Shortcode */function tablepress_add_shortcode_parameters_multi_filter_select( $default_atts ) { $default_atts['datatables_multi_filter_select'] = false; return $default_atts;} /** * Make sure that "table_foot" and "datatables_scrollX" are false, if "datatables_multi_filter_select" is true, * as the footer will be appended by the JS.

• Duplication of menu items with ViewPager and Fragments

  - by Julian

  I'm building an Android Application (minimum SDK Level 10, Gingerbread 2.3.3) with some Fragments in a ViewPager. I'm using ActionBarSherlock to create an ActionBar and android-viewpagertabs to add tabs to the ViewPager just like in the Market client. I have one global menu item that I want to be shown on every tab/fragment. On the first of the three tabs I want to have two additional menu items. But now two strange things happen: First if I start the app, everything seems to be fine, I can see all three menu items on the first page and only one item if i swipe to the second and third tab. But if I swipe back to the second tab from the third one, I can see all three items again which shouldn't happen. If I swipe back to the first and then again to the second tab, everything is fine again. The other strange thing is that every time I rotate the device, the menu items from the fragment are added again, even though they are already in the menu. Code of the FragmentActivity that displays the ViewPager and its tabs: public class MainActivity extends FragmentActivity { public static final String TAG = "MainActivity"; private ActionBar actionBar; private Adapter adapter; private ViewPager viewPager; private ViewPagerTabs tabs; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.volksempfaenger); actionBar = getSupportActionBar(); adapter = new Adapter(getSupportFragmentManager()); adapter.addFragment(getString(R.string.title_tab_subscriptions), SubscriptionGridFragment.class); // adding more fragments here viewPager = (ViewPager) findViewById(R.id.viewpager); viewPager.setAdapter(adapter); tabs = (ViewPagerTabs) findViewById(R.id.tabs); tabs.setViewPager(viewPager); } public static class Adapter extends FragmentPagerAdapter implements ViewPagerTabProvider { private FragmentManager fragmentManager; private ArrayList<Class<? extends Fragment>> fragments; private ArrayList<String> titles; public Adapter(FragmentManager fm) { super(fm); fragmentManager = fm; fragments = new ArrayList<Class<? extends Fragment>>(); titles = new ArrayList<String>(); } public void addFragment(String title, Class<? extends Fragment> fragment) { titles.add(title); fragments.add(fragment); } @Override public int getCount() { return fragments.size(); } public String getTitle(int position) { return titles.get(position); } @Override public Fragment getItem(int position) { try { return fragments.get(position).newInstance(); } catch (InstantiationException e) { Log.wtf(TAG, e); } catch (IllegalAccessException e) { Log.wtf(TAG, e); } return null; } @Override public Object instantiateItem(View container, int position) { FragmentTransaction fragmentTransaction = fragmentManager .beginTransaction(); Fragment f = getItem(position); fragmentTransaction.add(container.getId(), f); fragmentTransaction.commit(); return f; } } @Override public boolean onCreateOptionsMenu(Menu menu) { BaseActivity.addGlobalMenu(this, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { return BaseActivity.handleGlobalMenu(this, item); } } Code of the fragment that shall have its own menu items: public class SubscriptionGridFragment extends Fragment { private GridView subscriptionList; private SubscriptionListAdapter adapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setHasOptionsMenu(true); } // ... @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { inflater.inflate(R.menu.subscription_list, menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { // ... } }

• Why only one video shows up in ASP.NET Video panel ?

  - by user284523

  It is possible to have multiple videos with Flowplayer http://flowplayer.org/demos/installation/multiple-players.html To do so in ASP.NET DYNAMICALLY, one has to use a Panel (see http://idevwebs.com/Default.aspx?id=25): <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <!-- A minimal Flowplayer setup to get you started --> <!-- include flowplayer JavaScript file that does Flash embedding and provides the Flowplayer API. --> <script type="text/javascript" src="flowplayer-3.1.4.min.js"></script> <!-- page title --> <title>Minimal Flowplayer setup</title> </head><body> <form id="form1" runat="server"> <div id="page"> <h1>Minimal Flowplayer setup</h1> <p>View commented source code to get familiar with Flowplayer installation.</p> <!-- this A tag is where your Flowplayer will be placed. it can be anywhere --> <!-- player #1 --> <asp:Panel ID="panelVideo" runat="server"> </asp:Panel> <!-- this will install flowplayer inside previous A- tag. --> <script type="text/javascript"> flowplayer("player", "flowplayer-3.1.5.swf"); </script> <!-- after this line is purely informational stuff. does not affect on Flowplayer functionality --> <p> If you are running these examples <strong>locally</strong> and not on some webserver you must edit your <a href="http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html"> Flash security settings</a>. </p> <p class="less"> Select "Edit locations" &gt; "Add location" &gt; "Browse for files" and select flowplayer-x.x.x.swf you just downloaded. </p> <h2>Documentation</h2> <p> <a href="http://flowplayer.org/documentation/installation/index.html">Flowplayer installation</a> </p> <p> <a href="http://flowplayer.org/documentation/configuration/index.html">Flowplayer configuration</a> </p> <p> See this identical page on <a href="http://flowplayer.org/demos/example/index.htm">Flowplayer website</a> </p> </div> </form> </body></html> and then add video anchor dynamically public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { this.panelVideo.Controls.Add(new LiteralControl("<a href=\"" + "http://blip.tv/file/get/" + "KimAronson-TwentySeconds58192" + ".flv\" style=\"display:block;width:388px;height:230px\" id=\"player\"></a>")); this.panelVideo.Controls.Add(new LiteralControl("<a href=\"" + "http://blip.tv/file/get/" + "KimAronson-TwentySeconds67463" + ".flv\" style=\"display:block;width:388px;height:230px\" id=\"player\"></a>")); } } But it works only partially as the first video shows up not both. And all html below doesn't show up either.

• Business rule validation of hierarchical list of objects ASP.NET MVC

  - by SergeanT

  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#" ...

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.

• Serializing WPF DataTemplates and {Binding Expressions} (from PowerShell?)

  - by Jaykul

  Ok, here's the deal: I have code that works in C#, but when I call it from PowerShell, it fails. I can't quite figure it out, but it's something specific to PowerShell. Here's the relevant code calling the library (assuming you've added a reference ahead of time) from C#: public class Test { [STAThread] public static void Main() { Console.WriteLine( PoshWpf.XamlHelper.RoundTripXaml( "<TextBlock Text=\"{Binding FullName}\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"/>" ) ); } } Compiled into an executable, that works fine ... but if you call that method from PowerShell, it returns with no {Binding FullName} for the Text! add-type -path .\PoshWpf.dll [PoshWpf.Test]::Main() I've pasted below the entire code for the library, all wrapped up in a PowerShell Add-Type call so you can just compile it by pasting it into PowerShell (you can leave off the first and last lines if you want to paste it into a new console app in Visual Studio. To output (from PowerShell 2) as an executable, just change the -OutputType parameter to ConsoleApplication and the -OutputAssembly to PoshWpf.exe (or something). Thus, you can see that running the SAME CODE from the executable gives you the correct output. But running the two lines as above or manually calling [PoshWpf.XamlHelper]::RoundTripXaml or [PoshWpf.XamlHelper]::ConvertToXaml from PowerShell just doesn't seem to work at all ... HELP?! Add-Type -TypeDefinition @" using System; using System.ComponentModel; using System.Globalization; using System.Linq; using System.Windows; using System.Windows.Data; using System.Windows.Markup; namespace PoshWpf { public class Test { [STAThread] public static void Main() { Console.WriteLine( PoshWpf.XamlHelper.RoundTripXaml( "<TextBlock Text=\"{Binding FullName}\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"/>" ) ); } } public class BindingTypeDescriptionProvider : TypeDescriptionProvider { private static readonly TypeDescriptionProvider _DEFAULT_TYPE_PROVIDER = TypeDescriptor.GetProvider(typeof(Binding)); public BindingTypeDescriptionProvider() : base(_DEFAULT_TYPE_PROVIDER) { } public override ICustomTypeDescriptor GetTypeDescriptor(Type objectType, object instance) { ICustomTypeDescriptor defaultDescriptor = base.GetTypeDescriptor(objectType, instance); return instance == null ? defaultDescriptor : new BindingCustomTypeDescriptor(defaultDescriptor); } } public class BindingCustomTypeDescriptor : CustomTypeDescriptor { public BindingCustomTypeDescriptor(ICustomTypeDescriptor parent) : base(parent) { } public override PropertyDescriptorCollection GetProperties(Attribute[] attributes) { PropertyDescriptor pd; var pdc = new PropertyDescriptorCollection(base.GetProperties(attributes).Cast<PropertyDescriptor>().ToArray()); if ((pd = pdc.Find("Source", false)) != null) { pdc.Add(TypeDescriptor.CreateProperty(typeof(Binding), pd, new Attribute[] { new DefaultValueAttribute("null") })); pdc.Remove(pd); } return pdc; } } public class BindingConverter : ExpressionConverter { public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType) { return (destinationType == typeof(MarkupExtension)) ? true : false; } public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType) { if (destinationType == typeof(MarkupExtension)) { var bindingExpression = value as BindingExpression; if (bindingExpression == null) throw new Exception(); return bindingExpression.ParentBinding; } return base.ConvertTo(context, culture, value, destinationType); } } public static class XamlHelper { static XamlHelper() { // this is absolutely vital: TypeDescriptor.AddProvider(new BindingTypeDescriptionProvider(), typeof(Binding)); TypeDescriptor.AddAttributes(typeof(BindingExpression), new Attribute[] { new TypeConverterAttribute(typeof(BindingConverter)) }); } public static string RoundTripXaml(string xaml) { return XamlWriter.Save(XamlReader.Parse(xaml)); } public static string ConvertToXaml(object wpf) { return XamlWriter.Save(wpf); } } } "@ -language CSharpVersion3 -reference PresentationCore, PresentationFramework, WindowsBase -OutputType Library -OutputAssembly PoshWpf.dll Again, you can get an executable by just altering the last line like so: "@ -language CSharpVersion3 -reference PresentationCore, PresentationFramework, WindowsBase -OutputType ConsoleApplication -OutputAssembly PoshWpf.exe

• jQuery: Div elements are not showing up

  - by Legend

  I am adapting the Coverflow technique to work with a div. Following is the html: <html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> <style type="text/css" media="screen"> body,html { margin: 0; padding: 0; background: #000; height: 100%; color: #eee; font-family: Arial; font-size: 10px; } div.magnifyme { height: 80px; padding: 80px; position: absolute; top: 0px; left: 0px; width: 8000px; } div.wrapper { margin: 0px; height: 470px; /*border: 2px solid #999;*/ overflow: hidden; padding-left: 40px; right: 1px; width: 824px; position: relative; } div.container {position: relative; width: 854px; height: 480px; background: #000; margin: auto;} div.nav {position: absolute; top: 10px; width: 20%; height: 10%; right: 1px; } div.magnifyme div { position: absolute; width: 300px; height: 280px; float: left; margin: 5px; position: relative; border: 2px solid #999; background: #500; } </style> <script type="text/javascript" src="jquery-1.3.2.js"></script> <script type="text/javascript" src="ui.coverflow.js"></script> <script type="text/javascript"> $(function() { $("div.magnifyme").coverflow(); $("#add").click(function() { location.reload(); $(".magnifyme").append("<div id=\"div5\">hello world</div>"); $("div.magnifyme").coverflow(); }); }); </script> </head> <body> <div class="container"> <div class="wrapper"> <div class="magnifyme"> <div id="div0">This is div 0</div> <div id="div1">This is div 1</div> <div id="div2">This is div 2</div> <div id="div3">This is div 3</div> <div id="div4">This is div 4</div> </div> </div> <div class="nav"> <button type="button" id="add">Add to Deck</button> </div> </div> </body> </html> The coverflow function (included as a js file in the head section) is here. When I click the button, I was expecting it to add a DIV to the already present deck. For some reason, it doesn't show the newly added DIV. I tried calling the coverflow() function after I added the new element but that didn't work either. Is there any way I can make this work?

• Symfony2: validate an object that is not an entity

  - by Marronsuisse

  I am using CraueFormFlowBundle to have a multiple page form, and am trying to do some validation on some of the fields but can't figure out how to do this. The object that needs to be validated isn't an Entity, which is causing me trouble. I tried adding a collectionConstraint in the getDefaultOption function of my form type class, but this doesn't work as I get the "Expected argument of type array or Traversable and ArrayAccess" error. I tried with annotations in my object class, but they don't seem to be taken into account. Are annotations taken into account if the class isn't an entity? (i set enable_annotations to true) Anyway, what is the proper way to do this? Basically, I just want to validate that "age" is an integer... class PoemDataCollectorFormType extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { switch ($options['flowStep']) { case 6: $builder->add('msgCategory', 'hidden', array( )); $builder->add('msgFIB','text', array( 'required' => false, )); $builder->add('age', 'integer', array( 'required' => false, )); break; } } public function getDefaultOptions(array $options) { $options = parent::getDefaultOptions($options); $options['flowStep'] = 1; $options['data_class'] = 'YOP\YourOwnPoetBundle\PoemBuilder\PoemDataCollector'; $options['intention'] = 'my_secret_key'; return $options; } } EDIT: add code, handle validation with annotations As Cyprian, I was pretty sure that using annotations should work, however it doesn't... Here is how I try: In my Controller: public function collectPoemDataAction() { $collector = $this->get('yop.poem.datacollector'); $flow = $this->get('yop.form.flow.poemDataCollector'); $flow->bind($collector); $form = $flow->createForm($collector); if ($flow->isValid($form)) { .... } } In my PoemDataCollector class, which is my data class (service yop.poem.datacollector): class PoemDataCollector { /** * @Assert\Type(type="integer", message="Age should be a number") */ private $age; } EDIT2: Here is the services implementation: The data class (PoemDataCollector) seems to be linked to the flow class and not to the form.. Is that why there is no validation? <service id="yop.poem.datacollector" class="YOP\YourOwnPoetBundle\PoemBuilder\PoemDataCollector"> </service> <service id="yop.form.poemDataCollector" class="YOP\YourOwnPoetBundle\Form\Type\PoemDataCollectorFormType"> <tag name="form.type" alias="poemDataCollector" /> </service> <service id="yop.form.flow.poemDataCollector" class="YOP\YourOwnPoetBundle\Form\PoemDataCollectorFlow" parent="craue.form.flow" scope="request"> <call method="setFormType"> <argument type="service" id="yop.form.poemDataCollector" /> </call> </service> How can I do the validation while respecting the craueFormFlowBundle guidelines? The guidelines state: Validation groups To validate the form data class a step-based validation group is passed to the form type. By default, if getName() of the form type returns registerUser, such a group is named flow_registerUser_step1 for the first step. Where should I state my constraint to use those validation groups..? I tried: YOP\YourOwnPoetBundle\PoemBuilder\Form\Type\PoemDataCollectorFormType: properties: name: - MinLength: { limit: 5, message: "Your name must have at least {{ limit }} characters.", groups: [flow_poemDataCollector_step1] } sex: - Type: type: integer message: Please input a number groups: [flow_poemDataCollector_step6] But it is not taken into acount.
