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.

I start with an empty array collection and sure enough, the tile list is empty. When I add the first item to the new dataProvider, I see the last item from the previous dataProvider as the first entry in the list.
