The current "tree" section doesn't appear in the left-hand menu neither in the breadcrumb - just if I click "more on widgets" I'll get it in the overview..

I have stumbled across a really odd problem and I don't know how to solve it:

I want to handle drop events in a Tree, i.e. perform some checks on a dropped node. Simple, I thought, just connect your drop handler to the drop target's onDrop() function everytime a new node is created:

    onFilterTreeNodeAdded: function(message) {
        // register DND handler for new node
        var id = message.child.widgetId;
        var filterTree = dojo.widget.byId("FilterTree");
        var dndController = filterTree.controller.DNDController;
        var dropTarget = dndController.dropTargets[id];
        dojo.event.connect(dropTarget, "onDrop", this, "onFilterNodeDropped");
        
        // handle change event
        this.onFilterTreeChanged(message);
    }

However that does NOT work. My event handler is never called, but dropTarget.onDrop() is. I noticed that in the debugger the join-point object injected by dojo.event.connect() was not there when onDrop() is called, so my handler wouldn't be called. I realized that this is because onDrop() is called on a COPY of the dropTarget object referenced in dndController.dropTargets which doesn't know a thing about my event handler (I inserted an identity check in the Dojo onDrop() function and it always fails).

This is very inconvenient, I'm sure there must be a way to intercept onDrop() events on Trees?!
