Drag and Drop in TreeTableView

Hi

We are currently building a prototype application in order to evaluate
the NetBeans 4.0 Platform for use in a large project.

During this effort we ran into the following problem: There's no support
for reordering nodes using drag and drop in a TreeTableView (as opposed
to a BeanTreeView). The platform code for TreeTableView (package
org.openide.explorer.view) has the following lines:

    /* DnD is not implemented for treeTable.
     */
    public void setDragSource (boolean state) {
    }

    /* DnD is not implemented for treeTable.
     */
    public void setDropTarget (boolean state) {
    }

I tried naively to replace this with:

    /* DnD is not implemented for treeTable - fixed
     */
    public void setDragSource (boolean state) {
	super.setDragSource(state);
    }

    /* DnD is not implemented for treeTable - fixed
     */
    public void setDropTarget (boolean state) {
	super.setDropTarget(state);
    }

But that didn't solve the problem. Apparently there's more to it than
that. 

* Does anyone know why DnD was disabled (or not implemented) in
TreeTableView in the first place? 
* Can anyone outline what would be required to add support for DnD in a
TreeTableView?

Thanks!
