The user will then be able to drag (copy) these images out of the list onto another control. I've finally got the images showing up correctly (and not disappearing after scrolling the TileList) but they seem to disappear from the TileList at the start of a drag operation. I come from a .NET background and am just learning AS3/Flex, so if you see me using any anti-patterns here, feel

Many thanks! 回答1: For list based components, flex does this for efficiency. Imagine a dataprovider with 1000 rows, but the tile list only displays 9 at a time (3X3).

问题 I have a tilelist component using a custom ImageCell based item renderer. I know that at times some of the images it is trying to retrieve will not be found and I am able to handle this via an IEOrror listener on the custom ImageCell loader. However, if I set the data provider, then it is changed before all images have completed their loading or error process, the flash debug player throws up an unhandled #2044 error in firefox stating that an image could not be found.
