I get this same issue but when I add an itemRenderer with states. Use the same 
code as above but with this itemRenderer. Change one of the states of an 
itemRenderer and then refresh() the collection. It flips every time.

<?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" 
                                autoDrawBackground="true">
        <s:states>
                <s:State name="stateAAA" />
                <s:State name="stateBBB" />
        </s:states>
        <s:HGroup width="100%">
                <s:Label text="stateAAA" 
                                 click="{currentState='stateBBB'}" 
                                 includeIn="stateAAA" />
                <s:Label text="stateBBB" 
                                 click="{currentState='stateAAA'}"
                                 includeIn="stateBBB" />
                <s:Label text="({this.currentState})" fontStyle="italic" />
                <s:Label text="{data}"/>
        </s:HGroup>
</s:ItemRenderer>

I get this same issue but when I add an itemRenderer with states. I'm attaching 
a sample using the same code from above with a Renderer.
