[flexcoders] Re: TileList dataprovider change bug?
This is definitely a pointer in the right direction. I found that my item renderer was not redrawing things under certain conditions. Fixing that fixed the problem.

For now I am shelving TileList in favour of a custom component to do the job. I'll put together an isolated test case and see what is going on. If I find something I open a bug.

[flexcoders] Re: TileList dataprovider change bug?
Hmm, never had a problem like this with a TileList. You can try myOldArrayCollection.removeAll(), before setting to the new ArrayCollection. (Hack) Also, make sure that you reset any filterFunctions that you may be using. Perhaps there is something else that is not getting reset before you try to add; some kind of cache? Or, the problem is with the add logic. If the TileList clears, then the dataProvider is clear (filterFunction withstanding). I would look around a little wider, in addition to fucusing on the TileList. -TH --- In flexcoders@yahoogroups.com, "Ritu Raj Tiwari" wrote: > > Jake, > Thanks for your response, but this did not help.

Jake, Thanks for your response, but this did not help. I am still seeing the exact same behaviour. It is as if changing the data provider somehow does not really clean things out in the tile list. -Raj --- In flexcoders@yahoogroups.com, "j...@..." wrote: > > Instead of switching arraycollections, leave the arraycollection alone and > alter the arraycollection.source (Array).
