Say you have an HBox, and inside that HBox you have lots of little child HBoxes. Now, you want to rearrange the child HBoxes using drag and drop. Using Flex, it's pretty easy to enable drag/drop support. However, the dragover event seems to fire at odd points.
As I drag a child HBox around the main HBox, I sometimes see the invalid drag icon, even though it should be valid. If it disallowed dragging one child over another, I could understand that. But even that seems random, with some portions of the children showing as valid drag targets, and others not. With a small number of children, it was odd but not debilitating. With a large number of children, it became entirely untenable. If I have ten children, I can't drop the items anywhere except the first half of it's width. Is there another element to this that affects where an object becomes a drop target or not? Variable width perhaps? Padding? I'm at a loss.
