I inherited some code which supports drag and drop from a list to a node of a tree. Unfortunately it does not work when the tree is scrolled. Not only does the tree not autoscroll, but even if you scroll the target item into view before beginning the drag, incorrect nodes highlight.
I didn't see any code that's doing coordinate transformations, but did notice that there is a custom TreeItemRenderer, which contains the listeners for dragEnter etc. I'm guessing this is the root of the problem, since renderers are recycled. I've no idea why things were done this way, and am wondering if this is a legitimate idiom, or if I need to start over with listeners defined at the Tree level. Also, is autoscroll supported if you do things the right way?
