I have a repeater inside a component that is drawn by a HorizontalList. When I set the dataProvider from the dataChange event, the repeater isn't ready when the component first draws. So, I have a choice. I can use callLater(), which, as I understand it, is the correct method, or I can call the same function from dataChange and creationComplete, adding a check to see if the repeater exists yet.
When I do the double call (from both dataChange and creationComplete), everything looks exactly right on screen. When I use callLater, the HorizontalList is about 20 px wide and maybe 5 high. When the components finish drawing, you can see their upper left corners, so I presume everything is there, but it seems like Flex is no longer able to tell how big to make the containers. I've tried invalidateProperties(), invalidateDisplayList() and validateNow(), but nothing seems to work. Any ideas? TIA; Amy
