I figured it out. It has to do with how Repeater initializes it's
inner components. I guess Flex doesn't know the actual type of the
innercomponent until "repeatEnd" gets fired.
Please see the code below. Here init() is the callback for my
component's "creationComplete" event:
private function init():void
{
rp.addEventListener(FlexEvent.REPEAT_END,
function(event:FlexEvent):void
{
img.addEventListener(Event.COMPLETE, onImgComplete);
});
}
This way no complaint from compiler.
