    [CLOSED] drag and drop in tree panels question

    I want to add drag & drop support in a TreePanel. When the user drops a node I have to execute a server action. The drop action needs a server validation and in certain conditions (as determined on the server) the operation might be invalid. Is the rejection of the drop operation (expressed perhaps through parameters) following a server action currently supported? What I am getting at is I want the whole drag & drop operation (which involves the client action of dragging & dropping a node, and the server validation that is fired upon the client drag&drop) to act as one unit, i.e. if the server validation fails the node is not moved to its new parent even though the parent appeared to be a valid drop target initially.

    If this behavior is not supported then I will have to resort to some other tricks - probably refresh the tree from the server.

    Thanks
