Flex :: Itemrenderer - Image Switching Place In Tilelist?

I'm running into an odd issue with itemRenderers inside a TileList.Here is a working example without an itemRenderer: 152.org/flex/

Here is the broken version with an itemRenderer: 152.org/brokenExample/. (I don't have the rep to make both of these a link)Both examples have "View Source" enabled.To see the problem use the broken example, select an album and scroll down one row. Scroll back up and the images will be switched.If you try this on the working example it's fine.This seems to be a widely known bug, but I can't find a solution for it.

UPDATE: I started playing with this example again and found out something else. Turns out you don't have to override the data setter. You can create a new method in the itemRenderer that is set whenever the tile wants to refresh. So the trick is to not rely on the initialize or creationComplete methods.This is what I have for the itemRenderer in the Application.

<itemRenderers:ImageTile img="{data}"/>

This is the code I have in the itemRenderer.

public function set img(value:String) : void {
trace("setting source: " + value);
this.source = value;[code]....

I updated my example to reflex this change.
