I'm having problems with drag and drop, I wouldn't like to allow one node to be moved within one own subnode, for example:
the node 2 can't be moved to node 3, if this happen node 3 has a new subnode but has no parent. The same can't happen with the node 1 that can't be moved to node 2.
Is there a way to prevent this without to implement a method in my viewmodel?
or this is a bug in the compnent ?
I'm using AbstractTreeModel, because my tree can become very big and I want it to be loaded on demand, the most examples on the web are about DefaultTreeModel and I can't adapt this examples to my solution.

PS.: I already updated to zk 7.0 but the problem persist.
