I have a List component using multiple item renderers determined by the itemRendererFunction. When I set the data the first time, it works as expected. Then, when I set the data a second time with new data, it doesn’t call the itemRendererFunction and tries to reuse the current renderers even though they don’t match the data. Once I scroll, the function is called and the correct renderers are used. I tried calling invalidateDisplayList and such prior to setting the data, but that didn’t fix the problem. Any ideas?

    It turns out this is a Flex SDK bug. Peter DeHaan provided me with a workaround (re-setting the itemRendererFunction property after the dataProvider is set) and is filing it for a future release of the SDK.
