Flex TileList itemrenderer + scroll = HELL

I'm going insane over this issue. Basically, I have a TileList with a custom item renderer that has a TextInput in it. Let's say that the list can show 4 items at once, if there are 5 items and I edit the text on the first one, the fifth will be edited also. In general if an item is out of view, it will be change when I edit one that is showing.

Also, I had overriden the TileList class to expose the rendererArray property (so that I could access the texts on each renderer) but it will only return the renderers which are displayed.

Any help is appreciated. I need to know h开发者_高级运维ow to override this weird behaviour with itemrenderers that aren't currently displayed. Thanks.

Ok, if anyone runs into a similar issue, here is what you need to do:

First of all, avoid trying to iterate through the itemrenderers like I did. If you need a TextInput or another control on your TileList, make sure that these controls are bound to a property on your data object, otherwise off-screen items will have incorrect values since their itemrenderers will be recycled from the items that left the screen when you scrolled.

If you think it through, any requirement can be solved by iterating through the dataprovider instead of the itemrenderers.

Also, if you try to expose the rendererArray property like I did, notice that you will only be able to iterate through the itemrenderers that are currently displayed, since those that would belong to the items that are off-screen will not be created yet.

I hope this wasn't too confusing..
