Something I need to remember about ItemRenderers and the TileList control

From a high level perspective, scrolling is moving data through fixed itemRenderers, not by actually moving renderers off the visible area of
the screen.

I found this little bit of information hidden in this thread. After trying to extensively use my PageList component in a large application and with a dataProvider that had the potential of providing hundreds of items needing rendering I was noticing a very bad side effect. My application would continue to create a new instance of the itemRenderer for every item in the dataProvider and if the dataProvider was emptied ( ie: arrayCollection.removeAll() ) the itemRenderers would remain.

Back to the drawing board on that one. I hope to post a new PageList component soon as my application is not usable in it's current state.
