the following code throws the compile time error below:
<mx:Repeater id="rpt" dataProvider="{arr}">
<mx:RadioButtonGroup id="group" />
<mx:RadioButton groupName="group"/>
<mx:RadioButton groupName="group" />
</mx:Repeater>error: Unable to generate initialization code within Repeater, due to id or data binding on a component that is not a visual child. I'm not sure how your method would work in this scenario.
