Hi!
We ran into the same issue, the flex project was running properly in
flex 2 but when we migrated to flex 3 we had the exact same issue as
yours.
To fix that problem we got rid of these "new ClassFactory(...)", just
define your renderers like that:
<mx:TileList id="tilelist"
dataProvider="{ac}"
itemRenderer="mx.controls.Label" left="10"
right="10" bottom="99" top="70"/>
Hope this helps :)
