Thanks for the suggestion. In my case, I don't change the underlying data provider, though - I simply have an ArrayCollection set as the data provider for a List. When the filter function is set, the right thing happens: Only items in the list matching the filter criteria show. However, when at that point I click on a list item, the selected item sometimes "jumps," so to speak, to a position above where it originally was, and other items rearrange in the list. I don't have a sort function set for the ArrayCollection, btw.
I also noticed that this does not occur when the subset created with the filter function is small, i..e, 4-5 items or less. But when the subset is bigger (a dozen or more items), this occurs every time. And when the subset is very long (few dozen items), this makes the list unusable, as users cannot reliably select list items. I also verified this with a list that has no custom item renderer, btw. Yes, I'm using 2.0.1.
