  • Pass deeply nested element to function in JQuery

    - by klez
    I have this form: <form action="contact.php" method="post" id="contactform"> <ol> <li> <label for="name">First Name * </label> <input id="name" name="name" class="text" /> </li> <li> <label for="email">Your email * </label> <input id="email" name="email" class="text" /> </li> <li> <label for="company">Company</label> <input id="company" name="company" class="text" /> </li> <li> <label for="subject">Subject</label> <input id="subject" name="subject" class="text" /> </li> <li> <label for="message">Message * </label> <textarea id="message" name="message" rows="6" cols="50"></textarea> </li> <li class="buttons"> <input type="image" name="imageField" id="imageField" src="images/send.gif" /> </li> </ol> </form> This javascript function that does some basic validation: function validateRequired(field,alerttxt) { with (field) { if (value==null||value=="") { alert(alerttxt); return false; } return true; } } And this script (written with jquery) to intercept the submit event jQuery(document).ready(function(){ $('#contactform').submit(function(){ ... }); }); The problem is that, inside the last script I want to call validateRequired passing each required input/textarea (namely: name, email and message) as first parameter. I tried like this: validateRequired($('#name')); but it doesn't work. How can I do this?

  • sorting nested list, allow only li to be sorted witin the same ul

    - by Y.G.J
    what i want to achive is: sorting the main ul is working but not all the time - i will try to fix that my own but if there is a problem with the code here and not the one in proccess-sortable - tell me. moving li in the main ul is ok but the sub or the sub of the sub is having problem - i can drag something from one sub to it's sub or the other way too - i don't want that to happend. i want to be able to drag li and by selecting that one that only this ul group will send to proccess-sortable to be updated - how can i catch the specific ul of li i am draging? $(document).ready(function() { $("#test-list").sortable({ items: "> li", handle : '.handle', axis: 'y', opacity: 0.6, update : function () { var order = $('#test-list').sortable('serialize'); $("#info").load("process-sortable.asp?"+order+"&id=catid&order=orderid&table=tblCats"); } }); $("#test-sub").sortable({ containment: "ul", items: "li", handle : '.handle2', axis: 'y', opacity: 0.6, update : function () { var order = $('ul').sortable('serialize'); $("#info").load("process-sortable.asp?"+order+"&id=catid&order=orderid&table=tblCats"); } }); }); this is the html part <ul id="test-list"> <li id="listItem_10">first<img align="middle" src="Themes/arrow.png" class="handle" /></li> <li id="listItem_8">second<img align="middle" src="Themes/arrow.png" class="handle" /> <ul id="test-sub"> <li id="listItem_4><img align="middle" src="Themes/arrow.png" class="handle2" /></li> <li id="listItem_3"><img align="middle" src="Themes/arrow.png" class="handle2" /></li> <ul id="test-sub"> <li id="listItem_9"><img align="middle" src="Themes/arrow.png" class="handle2" /></li> </ul> </li> </ul> </li> </ul>

  • Working with hibernate/DAO problems

    - by Gandalf StormCrow
    Hello everyone here is my DAO class : public class UsersDAO extends HibernateDaoSupport { private static final Log log = LogFactory.getLog(UsersDAO.class); protected void initDao() { //do nothing } public void save(User transientInstance) { log.debug("saving Users instance"); try { getHibernateTemplate().saveOrUpdate(transientInstance); log.debug("save successful"); } catch (RuntimeException re) { log.error("save failed", re); throw re; } } public void update(User transientInstance) { log.debug("updating User instance"); try { getHibernateTemplate().update(transientInstance); log.debug("update successful"); } catch (RuntimeException re) { log.error("update failed", re); throw re; } } public void delete(User persistentInstance) { log.debug("deleting Users instance"); try { getHibernateTemplate().delete(persistentInstance); log.debug("delete successful"); } catch (RuntimeException re) { log.error("delete failed", re); throw re; } } public User findById( java.lang.Integer id) { log.debug("getting Users instance with id: " + id); try { User instance = (User) getHibernateTemplate() .get("project.hibernate.Users", id); return instance; } catch (RuntimeException re) { log.error("get failed", re); throw re; } } } Now I wrote a test class(not a junit test) to test is everything working, my user has these fields in the database : userID which is 5characters long string and unique/primary key, and fields such as address, dob etc(total 15 columns in database table). Now in my test class I intanciated User added the values like : User user = new User; user.setAddress("some address"); and so I did for all 15 fields, than at the end of assigning data to User object I called in DAO to save that to database UsersDao.save(user); and save works just perfectly. My question is how do I update/delete users using the same logic? Fox example I tried this(to delete user from table users): User user = new User; user.setUserID("1s54f"); // which is unique key for users no two keys are the same UsersDao.delete(user); I wanted to delete user with this key but its obviously different can someone explain please how to do these. thank you

  • Is Delete cascade possible in ravendb

    - by user1811801
    Still just a starter in ravendb. I have a doubt whether raven db supports some kind of referential integrity. Here is my doubt and work.. I have document type screens as below public class Screens { public String Id { get; set; } public String ScreenName { get; set; } } And Another document named RightsDeclaration as below public class RightsDeclaration { public RightsDeclaration() { _screenrights = new List<ScreenRight>(); } public String Id { get; set; }// Role Name List<ScreenRight> _screenrights; public List<ScreenRight> ScreenRights { get { return _screenrights; } set { _screenrights = value; } } } Now the screen rights class looks like below with the screen name field as below public class ScreenRight : { public String ScreenName { get; set; } public Boolean Create { get; set; } public Boolean Read { get; set; } public Boolean Update { get; set; } public Boolean Delete { get; set; } public Boolean Approve { get; set; } public Boolean Access { get; set; } public Boolean Print { get; set; } public Boolean Email { get; set; } } Now first i will create some list of screens and then i assign rights for each role with mentioning what is the screen name and list of rights. up to this point everything goes fine. Now in a scenario where if i would delete the screen name in screens class but then the screen rights for that screen still exists in the rights declaration. is it possible to delete the corresponding screen rights from userrights document too? if so please mention the query or idea to do the above.. Thanks in advance..

  • Generic linked list in c++

    - by itsaboy
    I have been struggling for too long a time now with a rather simple question about how to create a generic linked list in c++. The list should be able contain several types of structs, but each list will only contain one type of struct. The problem arises when I want to implement the getNode() function [see below], because then I have to specify which of the structs it should return. I have tried to substitute the structs with classes, where the getNode function returns a base class that is inherited by all the other classes, but it still does not do the trick, since the compiler does not allow the getNode function to return anything but the base class then. So here is some code snippet: typedef struct struct1 { int param1; (...) } struct1; typedef struct struct2 { double param1; (...) } struct2; typedef struct node { struct1 data; node* link; } node; class LinkedList { public: node *first; int nbrOfNodes; LinkedList(); void addNode(struct1); struct1 getNode(); bool isEmpty(); }; LinkedList::LinkedList() { first = NULL; nbrOfNodes = 0; } void LinkedList::addNode(struct1 newData) { if (nbrOfNodes == 0) { first = new node; first->data = newData; } else { node *it = first; for (int i = 0; i < nbrOfNodes; i++) { it = it->link; } node *newNode = new node; newNode->data = newData; it->link = newNode; } nbrOfNodes++; } bool LinkedList::isEmpty() { return !nbrOfNodes; } struct1 LinkedList::getNode() { param1 returnData = first->data; node* deleteNode = first; nbrOfNodes--; if (nbrOfNodes) first = deleteNode->link; delete deleteNode; return returnData; } So the question, put in one sentence, is as follows: How do I adjust the above linked list class so that it can also be used for struct2, without having to create a new almost identical list class for struct2 objects? As I said above, each instance of LinkedList will only deal with either struct1 or struct2. Grateful for hints or help

  • Arrays become null after passing to function in PHP

    - by William
    So when I pass my filled arrays to the function createform the form is created with $max_avatars options, but they have no name or value. Why are my arrays becoming null? <?php $avatar_image_name = array('hacker','samurai','cool','happy','thatsnice','angry','tv','bang'); $avatar_name = array('Hacker','Samurai','Cool','Happy','That\'s nice','Angry','TV','Bang'); $max_avatars = 6; createform($max_avatars, $avatar_image_name, $avatar_name); ?> The function createform: function createform($max_avatars, $avatar_image_name, $avatar_name) { $string ='<table id="formtable"> <tr><td class="formtext">Name:</td><td><input type="text" name=name size=25 /></td></tr> <tr><td class="formtext">Trip:</td><td><input type="text" name=trip size=25 /> (<font style="color: #ff0000">Don\'t use your password</font>)</td></tr> <tr><td class="formtext">Comment</td><td><textarea name=post rows="4" cols="50"></textarea></td></tr> <tr><td class="formtext">Avatar:</td> <td> <select name=avatar>'; for($i = 0; $i < $max_avatars; $i++){ $string = ($string .

  • How to get started with testing(jMock)

    - by London
    Hello, I'm trying to learn how to write tests. I'm also learning Java, I was told I should learn/use/practice jMock, I've found some articles online that help to certain extend like : http://www.theserverside.com/news/1365050/Using-JMock-in-Test-Driven-Development http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock And most articles I found was about test driven development, write tests first then write code to make the test pass. I'm not looking for that at the moment, I'm trying to write tests for already existing code with jMock. The official documentation is vague to say the least and just too hard for me. Does anybody have better way to learn this. Good books/links/tutorials would help me a lot. thank you EDIT - more concrete question : http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock - from this article Tried this to mock this simple class : import java.util.Map; public class Cache { private Map<Integer, String> underlyingStorage; public Cache(Map<Integer, String> underlyingStorage) { this.underlyingStorage = underlyingStorage; } public String get(int key) { return underlyingStorage.get(key); } public void add(int key, String value) { underlyingStorage.put(key, value); } public void remove(int key) { underlyingStorage.remove(key); } public int size() { return underlyingStorage.size(); } public void clear() { underlyingStorage.clear(); } } Here is how I tried to create a test/mock : public class CacheTest extends TestCase { private Mockery context; private Map mockMap; private Cache cache; @Override @Before public void setUp() { context = new Mockery() { { setImposteriser(ClassImposteriser.INSTANCE); } }; mockMap = context.mock(Map.class); cache = new Cache(mockMap); } public void testCache() { context.checking(new Expectations() {{ atLeast(1).of(mockMap).size(); will(returnValue(int.class)); }}); } } It passes the test and basically does nothing, what I wanted is to create a map and check its size, and you know work some variations try to get a grip on this. Understand better trough examples, what else could I test here or any other exercises would help me a lot. tnx

  • dojo layout tutorial dor version 1.7 doesn't work for 1.7.2

    - by Sheena
    This is sortof a continuation to dojo1.7 layout acting screwy. So I made some working widgets and tested them out, i then tried altering my work using the tutorial at http://dojotoolkit.org/documentation/tutorials/1.7/dijit_layout/ to make the layout nice. After failing at that in many interesting ways (thus my last question) I started on a new path. My plan is now to implement the layout tutorial example and then stick in my widgets. For some reason even following the tutorial wont work... everything loads then disappears and I'm left with a blank browser window. Any ideas? It just struck me that it could be browser compatibility issues, I'm working on Firefox 13.0.1. As far as I know Dojo is supposed to be compatible with this... anyway, have some code: HTML: <body class="claro"> <div id="appLayout" class="demoLayout" data-dojo-type="dijit.layout.BorderContainer" data-dojo-props="design: 'headline'"> <div class="centerPanel" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region: 'center'"> <div> <h4>Group 1 Content</h4> <p>stuff</p> </div> <div> <h4>Group 2 Content</h4> </div> <div> <h4>Group 3 Content</h4> </div> </div> <div class="edgePanel" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region: 'top'"> Header content (top) </div> <div id="leftCol" class="edgePanel" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region: 'left', splitter: true"> Sidebar content (left) </div> </div> </body> Dojo Configuration: var dojoConfig = { baseUrl: "${request.static_url('mega:static/js')}", //this is in a mako template tlmSiblingOfDojo: false, packages: [ { name: "dojo", location: "libs/dojo" }, { name: "dijit", location: "libs/dijit" }, { name: "dojox", location: "libs/dojox" }, ], parseOnLoad: true, has: { "dojo-firebug": true, "dojo-debug-messages": true }, async: true }; other js stuff: require(["dijit/layout/BorderContainer", "dijit/layout/TabContainer", "dijit/layout/ContentPane", "dojo/parser"]); css: html, body { height: 100%; margin: 0; overflow: hidden; padding: 0; } #appLayout { height: 100%; } #leftCol { width: 14em; }

  • Assign an existing click event function to another click event using jquery

    - by Peter Delahunty
    Ok so i have some html like this: <div id="navigation"> <ul> <li> <a>tab name</a> <span class="delete-tab">X</span> </li> <li> <a>tab name</a> <span class="delete-tab">X</span> </li> <li> <a>tab name</a> <span class="delete-tab">X</span> </li> <li class="selected"> <a>tab name</a> <span class="tab-del-btn">X</span> </li> </ul> </div> I then have javascript that is excuted on the page that i do not control (this is in liferay portal). I want to then manipulate things afterwards with my own custom javascript. SO... For each of the span.delete-tab elements an on-click event function has been assign earlier. It is the same function call for each span. I want to take that function (any) and call it from the click event of the span.tab-del-btn ? This is what i tried to do: var navigation = jQuery('#navigation'); var navTabs = navigation.find('.delete-tab'); var existingDeleteFunction = null; navTabs.each(function (i){ var tab = jQuery(this); existingDeleteFunction = tab.click; }); var selectedTab = jQuery('#navigation li.selected'); var deleteBtn = selectedTab.find('.tab-del-btn'); deleteBtn.click(function(event){ existingDeleteFunction.call(this); }); It does not work though. existingDeleteFunction is not the original function it is some jquery default function. Any ideas?

  • How to obtain a pointer out of a C++ vtable?

    - by Josh Haberman
    Say you have a C++ class like: class Foo { public: virtual ~Foo() {} virtual DoSomething() = 0; }; The C++ compiler translates a call into a vtable lookup: Foo* foo; // Translated by C++ to: // foo->vtable->DoSomething(foo); foo->DoSomething(); Suppose I was writing a JIT compiler and I wanted to obtain the address of the DoSomething() function for a particular instance of class Foo, so I can generate code that jumps to it directly instead of doing a table lookup and an indirect branch. My questions are: Is there any standard C++ way to do this (I'm almost sure the answer is no, but wanted to ask for the sake of completeness). Is there any remotely compiler-independent way of doing this, like a library someone has implemented that provides an API for accessing a vtable? I'm open to completely hacks, if they will work. For example, if I created my own derived class and could determine the address of its DoSomething method, I could assume that the vtable is the first (hidden) member of Foo and search through its vtable until I find my pointer value. However, I don't know a way of getting this address: if I write &DerivedFoo::DoSomething I get a pointer-to-member, which is something totally different. Maybe I could turn the pointer-to-member into the vtable offset. When I compile the following: class Foo { public: virtual ~Foo() {} virtual void DoSomething() = 0; }; void foo(Foo *f, void (Foo::*member)()) { (f->*member)(); } On GCC/x86-64, I get this assembly output: Disassembly of section .text: 0000000000000000 <_Z3fooP3FooMS_FvvE>: 0: 40 f6 c6 01 test sil,0x1 4: 48 89 74 24 e8 mov QWORD PTR [rsp-0x18],rsi 9: 48 89 54 24 f0 mov QWORD PTR [rsp-0x10],rdx e: 74 10 je 20 <_Z3fooP3FooMS_FvvE+0x20> 10: 48 01 d7 add rdi,rdx 13: 48 8b 07 mov rax,QWORD PTR [rdi] 16: 48 8b 74 30 ff mov rsi,QWORD PTR [rax+rsi*1-0x1] 1b: ff e6 jmp rsi 1d: 0f 1f 00 nop DWORD PTR [rax] 20: 48 01 d7 add rdi,rdx 23: ff e6 jmp rsi I don't fully understand what's going on here, but if I could reverse-engineer this or use an ABI spec I could generate a fragment like the above for each separate platform, as a way of obtaining a pointer out of a vtable.

  • Advice/suggestions for my first project PHP Classes

    - by Philip
    Hi guys, Any advice is welcome! I have a very limited understanding of php classes but below is my starting point for the route I would like to take. The code is a reflection of what I see in my head and how I would like to go about business. Does my code even look ok, or am I way off base? What are your thoughts, how would you go about achieving such a task as form-validate-insertquery-sendmail-return messages and errors?

  • Changing tabs in android

    - by Pavel
    Hi guys. Can someone please tell me how to change tab by clicking on element INSIDE the tab? I already tried it with global data. The code looks like this: public class Tabs extends TabActivity { int tabNumber = 0; private TabHost tabHost; int returnedTabNumber = 0; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); // Resource object to get Drawables tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Resusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, Tribocracy.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("map").setIndicator("Map", res.getDrawable(R.drawable.ic_tab_artists)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, Areas.class); spec = tabHost.newTabSpec("areas").setIndicator("Areas", res.getDrawable(R.drawable.ic_tab_albums)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, Settings.class); spec = tabHost.newTabSpec("settings").setIndicator("Settings", res.getDrawable(R.drawable.ic_tab_albums)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTab(tabNumber); } protected void onResume() { super.onResume(); GlobalData globalData = ((GlobalData)getApplicationContext()); returnedTabNumber = globalData.getTabNumber(); tabHost.setCurrentTab(returnedTabNumber); } } The global adapter looks like this: public class GlobalData extends Application { //---------------------------------------------------- private int Point1; //define the vars here private int Point2; //define the vars here private int Point3; //define the vars here private int Point4; //define the vars here private int Point5; //define the vars here private int Point6; //define the vars here private int tabNumber; public int getTabNumber() //getter of the value { return tabNumber; } public int setTabNumber(int number) //setter of the value { tabNumber = number; return tabNumber; } } Now when I'm trying to change tab in my ListActivity tab by clicking on one of the items it doesn't do anything and stays on the ListActivity tab. Perhaps I shouldn't use onResume() here. Basically I want to go to first tab when I click on one of the items in the list. Please help!

  • I have to select the checkbox two times to check/uncheck in jTable

    - by 117526709403775781607
    I have a jTable code i intend to use, but the problem with it is that when i click on the checkbox once it doesn't select/deselect it, instead i have to click twice.

  • How can I implement NotOfType<T> in LINQ that has a nice calling syntax?

    - by Lette
    I'm trying to come up with an implementation for NotOfType, which has a readable call syntax. NotOfType should be the complement to OfType<T> and would consequently yield all elements that are not of type T My goal was to implement a method which would be called just like OfType<T>, like in the last line of this snippet: public abstract class Animal {} public class Monkey : Animal {} public class Giraffe : Animal {} public class Lion : Animal {} var monkey = new Monkey(); var giraffe = new Giraffe(); var lion = new Lion(); IEnumerable<Animal> animals = new Animal[] { monkey, giraffe, lion }; IEnumerable<Animal> fewerAnimals = animals.NotOfType<Giraffe>(); However, I can not come up with an implementation that supports that specific calling syntax. This is what I've tried so far: public static class EnumerableExtensions { public static IEnumerable<T> NotOfType<T>(this IEnumerable<T> sequence, Type type) { return sequence.Where(x => x.GetType() != type); } public static IEnumerable<T> NotOfType<T, TExclude>(this IEnumerable<T> sequence) { return sequence.Where(x => !(x is TExclude)); } } Calling these methods would look like this: // Animal is inferred IEnumerable<Animal> fewerAnimals = animals.NotOfType(typeof(Giraffe)); and // Not all types could be inferred, so I have to state all types explicitly IEnumerable<Animal> fewerAnimals = animals.NotOfType<Animal, Giraffe>(); I think that there are major drawbacks with the style of both of these calls. The first one suffers from a redundant "of type/type of" construct, and the second one just doesn't make sense (do I want a list of animals that are neither Animals nor Giraffes?). So, is there a way to accomplish what I want? If not, could it be possible in future versions of the language? (I'm thinking that maybe one day we will have named type arguments, or that we only need to explicitly supply type arguments that can't be inferred?) Or am I just being silly?

  • C# Property Access vs Interface Implementation

    - by ehdv
    I'm writing a class to represent a Pivot Collection, the root object recognized by Pivot. A Collection has several attributes, a list of facet categories (each represented by a FacetCategory object) and a list of items (each represented by a PivotItem object). Therefore, an extremely simplified Collection reads: public class Collection { private List<FacetCategory> categories; private List<PivotItem> items; // other attributes } What I'm unsure of is how to properly grant access to those two lists. Because declaration order of both facet categories and items is visible to the user, I can't use sets, but the class also shouldn't allow duplicate categories or items. Furthermore, I'd like to make the Collection object as easy to use as possible. So my choices are: Have Collection implement IList<PivotItem> and have accessor methods for FacetCategory: In this case, one would add an item to Collection foo by writing foo.Add(bar). This works, but since a Collection is equally both kinds of list making it only pass as a list for one type (category or item) seems like a subpar solution. Create nested wrapper classes for List (CategoryList and ItemList). This has the advantage of making a consistent interface but the downside is that these properties would no longer be able to serve as lists (because I need to override the non-virtual Add method I have to implement IList rather than subclass List. Implicit casting wouldn't work because that would return the Add method to its normal behavior. Also, for reasons I can't figure out, IList is missing an AddRange method... public class Collection { private class CategoryList: IList<FacetCategory> { // ... } private readonly CategoryList categories = new CategoryList(); private readonly ItemList items = new ItemList(); public CategoryList FacetCategories { get { return categories; } set { categories.Clear(); categories.AddRange(value); } } public ItemList Items { get { return items; } set { items.Clear(); items.AddRange(value); } } } Finally, the third option is to combine options one and two, so that Collection implements IList<PivotItem> and has a property FacetCategories. Question: Which of these three is most appropriate, and why?

  • jQuery: form input values turns up undefined

    - by Seerumi
    Having problem with this bit of code qith jQuery. it should pick the values from current form and then submit them, but when I try to get them with jQuery they always turn up undefined. I know the SQL results are fine since they show correctly in HTML table, so it must be my inferior javascript skills. New with jQuery and I'm at loss :( PHP/HTML: echo "<table>\n" while ($row = odbc_fetch_array($query)) { echo "<form class='catForm'>\n"; echo "<input type=hidden class='catID' name='catID' value='".$row['running_id']."'/>\n"; echo "<tr>\n"; echo "<td>".$row['running_id']."</td>\n"; echo "<td>".$row['site_id']."</td>\n"; echo "<td>".$row['main_category']."</td>\n"; echo "<td>".$row['map_name']."</td>\n"; echo "<td><input type=textfield class='bCatID' value='".$row['mapping_id']."' size=6/></td>\n"; echo "<td><input type=submit class='saveCat' value='Save'/></td>\n"; echo "<td><input type=submit class='killCat' value='Delete' /></td>\n"; echo "</tr>\n"; echo "</form>\n"; } echo "</table>"; jQuery: $(".catForm").submit(function () { var id = $(this).find('.catID').val(); var bCatID = $(this).find('.bCatID').val(); var dataString = 'id='+id+'&bCatID='+bCatID; $.ajax({ type: "POST", url: 'adminUI/bin/updateSCategories.php', dataType : 'json', data: dataString, success: function(data) { if (data.error == true) $('.failure').html("Error, save failed.").show().fadeOut(2000); if (data.error == false) $('.success').html("Saved succesfully").show().fadeOut(2000); }, error: function(XMLHttpRequest, textStatus, errorThrown) { $('.failure').html("Error, save failed.").show().fadeOut(2000); } }); return false; }); RESULT: id: undefined bCatID: undefined

  • How do I use ViewScripts on Zend_Form File Elements?

    - by Sonny

  • Abstract mapping with custom JiBX marshaller

    - by aweigold
    I have created a custom JiBX marshaller and verified it works. It works by doing something like the following: <binding xmlns:tns="http://foobar.com/foo" direction="output"> <namespace uri="http://foobar.com/foo" default="elements"/> <mapping class="java.util.HashMap" marshaller="com.foobar.Marshaller1"/> <mapping name="context" class="com.foobar.Context"> <structure field="configuration"/> </mapping> </binding> However I need to create multiple marshallers for different HashMaps. So I tried to reference it with abstract mapping like this: <binding xmlns:tns="http://foobar.com/foo" direction="output"> <namespace uri="http://foobar.com/foo" default="elements"/> <mapping abstract="true" type-name="configuration" class="java.util.HashMap" marshaller="com.foobar.Marshaller1"/> <mapping abstract="true" type-name="overrides" class="java.util.HashMap" marshaller="com.foobar.Marshaller2"/> <mapping name="context" class="com.foobar.Context"> <structure map-as="configuration" field="configuration"/> <structure map-as="overrides" field="overrides"/> </mapping> </binding> However when doing so, when I attempt to build the binding, I receive the following: Error during code generation for file "E:\project\src\main\jibx\foo.jibx" - this may be due to an error in your binding or classpath, or to an error in the JiBX code My guess is that either I'm missing something I need to implement to enable my custom marshaller for abstract mapping, or custom marshallers do not support abstract mapping. I have found the IAbstractMarshaller interface in the JiBX API (http://jibx.sourceforge.net/api/org/jibx/runtime/IAbstractMarshaller.html), however the documentation seems unclear to me on if this is what I need to implement, as well as how it works if so. I have not been able to find an implementation of this interface to work off of as an example. My question is, how do you do abstract mapping with custom marshallers (if it's possible)? If it is done via the IAbstractMarshaller interface, how does it work and/or how should I implement it?

  • CSS Collapsing/Hiding divs with no data in <span>

    - by Chance
    I am trying to display an address which includes the following information: Title, division, address1, address2, town/state/zip, and country (5 seperate lines worth of data). The problem is sometimes the company may only have the title, address1, and town/state/zip yet other times it may be all but address2. This is determined upon a db record request server side. Therefore how can I make my output look proper when some of my labels will be blank? I would like div's that contain an empty span to be essentially collapsed/removed. My only idea of how was to use jquery and a selector to find all divs with blank spans (since thats all an asp.net label really is) and then remove those divs however this seems like such bad form. Is there any way to do this with css? Possible Code would be something like: $('span:empty:only-child').parent('div').remove(); Picture Examples (Ignore spacing/indentation issues which I will fix) Missing Division, Address2, and Country All Possible Fields The Html <asp:Label runat="server" ID="lblBillingAddressHeader" CssClass="lblBillingAddressHeader" Text="Billing Address:" /> <div style="position:relative; top:150px; left: 113px;"> <div class="test"> <asp:Label runat="server" ID="lblBillingDivision" CssClass="lblBillingShippingDivisionFont" /> </div> <div class="test"> <asp:Label runat="server" ID="lblBillingAddress" CssClass="lblBillingShippingFont" /> </div> <div class="test"> <asp:Label runat="server" ID="lblBillingAddress2" CssClass="lblBillingShippingFont" /> </div> <div class="test"> <asp:Label runat="server" ID="lblBillingAddress3" CssClass="lblBillingShippingFont" /> </div> <div class="test"> <asp:Label runat="server" ID="lblBillingAddress4" CssClass="lblBillingShippingFont" /> </div> </div> The CSS .test { position: relative; top: 0px; left: 0px; height: 12px; width: 300px; } .lblBillingShippingDivisionFont { font-size: small; font-weight: bold; } .lblBillingShippingFont { font-size: 10.6px; }

  • ASP.NET MVC 2: Linq to SQL entity w/ ForeignKey relationship and Default ModelBinder strangeness

    - by Simon
    Once again I'm having trouble with Linq to Sql and the MVC Model Binder. I have Linq to Sql generated classes, to illustrate them they look similar to this: public class Client { public int ClientID { get; set; } public string Name { get; set; } } public class Site { public int SiteID { get; set; } public string Name { get; set; } } public class User { public int UserID { get; set; } public string Name { get; set; } public int? ClientID { get; set; } public EntityRef<Client> Client { get; set; } public int? SiteID { get; set; } public EntityRef<Site> Site { get; set; } } The 'User' has a relationship with the 'Client' and 'Site . The User class has nullable ClientIDs and SiteIDs because the admin users are not bound to a Client or Site. Now I have a view where a user can edit a 'User' object, the view has fields for all the 'User' properties. When the form is submitted, the appropiate 'Save' action is called in my UserController: public ActionResult Save(User user, FormCollection form) { //form['SiteID'] == 1 //user.SiteID == 1 //form['ClientID'] == 1 //user.ClientID == null } The problem here is that the ClientID is never set, it is always null, even though the value is in the FormCollection. To figure out whats going wrong I set breakpoints for the ClientID and SiteID getters and setters in the Linq to Sql designer generated classes. I noticed the following: SiteID is being set, then ClientID is being set, but then the Client EntityRef property is being set with a null value which in turn is setting the ClientID to null too! I don't know why and what is trying to set the Client property, because the Site property setter is never beeing called, only the Client setter is being called. Manually setting the ClientID from the FormCollection like this: user.ClientID = int.Parse(form["ClientID"].ToString()); throws a 'ForeignKeyReferenceAlreadyHasValueException', because it was already set to null before. The only workaround I have found is to extend the generated partial User class with a custom method: Client = default(EntityRef<Client>) but this is not a satisfying solution. I don't think it should work like this? Please enlighten me someone. So far Linq to Sql is driving me crazy! Best regards
