The largest hammer is invalidateList(). I"d be putting a listener for collectionChange on the dataprovider to see if you're getting notifications or not.

Interestingly I did find that if I change the TileList display dimensions to be very small then restore to original size this obviously forces the itemRenderer to refresh - there's gotta be a better way to force it without using a resize effect.
