title: Flex3: Custom Item Renderer does not listen to events dispatched by parent
body: <p>I have a List with a custom ItemRenderer. The ItemRenderer contains a Checkbox and a Label.
  The component with the List has a 'select all' checkbox.
  When the 'select all' checkbox is checked, it dispatches an event that each item should listen to in order to select its own checkbox.
  The eventlistener is added on creationComplete of each item, and the event is dispatched correctly when the 'select all' checkbox is selected, but the listener in the custom ItemRenderer does not listen.</p>
  
  <p>How do I make the ItemRenderer listen to an event that is dispatched in its parent??</p>
  
  <p>I'll add some code examples to clarify:</p>
  
  <pre><code>------- container ----------
  &lt;mx:VBox&gt;
     &lt;mx:Script&gt;
        &lt;![CDATA[
           public var user1 = new User(1, "Jack");
           public var user2 = new User(2, "John");
           public var user3 = new User(3, "Mary");
  
           [Bindable]
           public var users:ArrayCollection = new ArrayCollection([user1], [user2], [user3]);
  
           public static const SELECT_ALL_USERS:String = "selectAllUsers";
  
           private function selectAllChangeHandler():void
           {
              if (selectAll.selected)
                 dispatchEvent(new Event(SELECT_ALL_USERS,true));
           }
        ]]&gt;
     &lt;/mx:Script&gt;
     &lt;mx:CheckBox id="selectAll" change="{selectAllChangeHandler()}" /&gt;
     &lt;mx:List dataProvider="{users}" itemRenderer="myRenderer" /&gt;
  &lt;/mx:VBox&gt;
  
  
  ------- renderer ----------
  &lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;mx:HBox creationComplete="{init()}"&gt;
     &lt;mx:Script&gt;
        &lt;![CDATA[
           private function init():void
           {
              addEventListener (Container.SELECT_ALL, selectAllHandler, false, 0, true);
           }
  
           private function selectAllHandler():void
           {
              checkbox.selected=true;
           }
  
           private function selected(id:int):Boolean
           {
               return id==1 || id==3;
           }
        ]]&gt;
     &lt;/mx:Script&gt;
  
     &lt;mx:CheckBox id="checkbox" selected="{selected(data.id)}" /&gt;
     &lt;mx:Label text="{data.name}" /&gt;
  &lt;/mx:HBox&gt;
  </code></pre>
  
  <p>Please note that the users ArrayCollection or its containing user objects cannot be changed because I need the values later on.
  So when 'selectAll' is clicked, each checkbox in the list should also be checked.</p>
