Description

Steps to reproduce:
1. Create binding to ItemRenderer's labelDisplay property. For example:
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer 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:states>
<s:State name="normal" />
<s:State name="hovered" />
<s:State name="selected" />
</s:states>

<s:transitions>
<s:Transition toState="normal">
<s:AnimateColor target="

{this.labelDisplay}

" duration="300"/>
</s:Transition>
</s:transitions>

<s:Label id="labelDisplay" color.hovered="0xCCCCCC" color.selected="0xFFFFFF"/>

</s:ItemRenderer>

Actual Results:
Got a warning "data binding will not be able to detect asignments to 'labelDisplay'"

Expected Results:
no warning/errors

Workaround (if any):
make labelDisplay bindable
