I cannot get the beforedrop or drop listener to work. What I want to do is save the node, in the database on drop. Basically I am working on an interface to map old categories to new one. I created 2 trees (drap/drop enabled) now on the drop of nodes of first tree on the node of the second tree, I want an ajax call to update new category and mark it as mapped.
ExtJs 4 documentation is a bit scarce and the api is incomplete and I cannot find many examples of multiple tree drap and drop.
