You need to override the set data for your
ItemRenderer to update the value. If you use that init function it will only
update the renderers once and will never do it again. Item renderers are
re-used.

Subject: [flexcoders] TileList
dataprovider refresh Problem
Hi,
I've got some serious trouble using a TileList with Data-Binding. I
have a TileList to display a part of an XML and a selectbox to switch
betwenn different parts of this xml (chapters). The XMLListCollection
containing the content of the TileList is Bindable and even changes,
as you can see in the Debug-Textarea on the right side. But the
TileList even does not notice about changing it's (bindable)
dataprovider, all kinds of methods like invalidateData() or something
does not take any effect.
Does anybody has an idea, what the problem is?
