I need to redraw the items of my spark List at some times. I found list.datagroup.invalidateDisplayList() was the key and it worked fine when i used Flex 4.1 SDK compiler.
I recently migrated to Flex 4.5.1 SDK compiler and list.datagroup.invalidateDisplayList() no longer works, my spark List doesnt refresh.
I found nothing about that problem on forums, that's why i'd like to know if anybody had the same issue ?
Is there another way to refresh my List in Flex 4.5.1 ?
Well, setting itemRenderer to null and re assigning it works fine. But I m still wondering, for information, if someone knows why list.datagroup.invalidateDisplayList() doesn't work ?
