Description

Steps to reproduce:

The following application shows "Hello..." on one line, and "...world" on the next. However, add id="contentGroup" to the second Group, and nothing displays, not even "Hello...". The window will be blank even if the visible property of the first Group is set to false.

<?xml version="1.0" encoding="utf-8"?>
<s:Application
backgroundColor="0x00ff00"
xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">

<s:Label
x="100" y="100"
fontSize="24"
text="Hello..."/>

<s:Group id="scrollerParentGroup"
visible="true">

<s:Scroller>

<!-- add id="contentGroup" to the following, and the whole screen is blank-->
<s:Group>

<s:Label
x="100" y="150"
fontSize="24"
text="...world"/>

</s:Group>
</s:Scroller>
</s:Group>

</s:Application>

Expected Results:

"Hello..." and "...world" should both be displayed, even if the second group has an id. However, if it's not legal to set the id of a Group inside a Scroller, then Flex should throw an error.
