I always had the redX icon there, even when I called the acceptDragDrop, and the drop was excepted too. The only way I could find to solve the problem was leaving out the: dropEnabled="true" on the Tree. It is really strange, because I thought that this is mandatory to be able to drop on the Tree. Below is my test code in case you are interested.
