I just implemented the same thing. What I did was have data in the XML elements that differentiated what kind of node they were (topic and article in my case) and that told me the parent topic of the selected node (using parent topic id of 0 for a top level topic). This way you can compare data between the dragSource's dragItems and the item that exists in the tree at the calculatedDropIndex. Through this comparison you'll know if you're dropping onto a branch or leaf node and can handle it appropriately.
