This sounds like a recycling problem. It really depends on what you're doing in your set data function. Take a look at these links and see if they help http://www.adobe.com/devnet/flex/articles/itemrenderers_pt1.html? devcon=f1 (and go on and read part 2 as well) http://blogs.adobe.com/aharui/2007/03/thinking_about_item_renderers_1. html If not, post back.
