      Steps to reproduce:
      1. Run the following code:
      <?xml version="1.0" encoding="utf-8"?>
      <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
      xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
      import mx.collections.ArrayCollection;
      import mx.events.FlexEvent;

      protected function applicationCompleteHandler(event:FlexEvent):void
      testCombo.dataProvider = new ArrayCollection([

      {label:"Short item", someProperty:"foo"}


      {label:"This is a much longer item ! It would throw a RTE", someProperty:"bar"}


      {label:"This is another sample text", someProperty:"foobar"}

      testCombo2.dataProvider = new ArrayCollection([

      {label:"Short item", someProperty:"foo"}


      {label:"This is a much longer item ! It would throw a RTE", someProperty:"bar"}


      {label:"This is another sample text", someProperty:"foobar"}



      <s:DropDownList id="testCombo" labelField="label" horizontalCenter="0" verticalCenter="0" width="300">
      <s:HGroup verticalAlign="middle" width="100%">
      <s:Label text="

      <s:Label text="{data.someProperty}"/>

      <s:ComboBox id="testCombo2" labelField="label" horizontalCenter="0" verticalCenter="50" width="300">
      <s:HGroup verticalAlign="middle" width="100%">
      <s:Label text="{data.label}

      <s:Label text="



      2. In the DropDownList, select the 2nd or 3rd item

      Actual Results:
      The spark Label class throws a 1069 error (translated from French):
      ReferenceError: Error #1069: Property -1 cannot be found on _AS3_.vec.Vector.<flash.display::DisplayObject> and there is no default value.

      Expected Results:

      • No RTE
      • The item is actually selected

      Workaround (if any):
      Not found. Tried the following things, none of them work:

      • replace the inline renderer with an external file renderer
      • use plain strings as items in the ArrayCollection
      • set the dataprovider from MXML rather than from code

      More info:

      • As you can see, selecting the first item in the list is working correctly, it seems that the problem is related to the lenght of the item renderer
      • The ComboBox is working perfectly with the same configuration
      • I'm using flash player debugger version 10.1 beta
      • JDK is Apple's 1.6 latest release
