Ext.tree.ViewDDPlugin beforedrop event not working accordingly the API docs

[radtad]

I've reported the problem as a ticket (for Ext.tree.plugin.TreeViewDragDropView, ptype: treeviewdragdrop).

I've got the following response, and have successfully applied the patch.

It will be fixed in 4.1 since it's an API change.

Where are you specifically are you putting this? I added this to Ext.tree.plugin.TreeViewDragDropView and it still doesn't work for me. Do you have a link to the bug you submitted by chance?

I have had some trouble figuring out where to put the override in an Ext 4 MVC application. The launch method of Ext.application seems to be a good place, so:

,launch: function() {

//... some other stuff here

Ext.view.DropZone.override({
            onNodeDrop : function (node, dragZone, e, data) {    var me = this,
                dropHandled = false,
                
                // Create a closure to perform the operation which the event handler may use.
                // Users may now set the wait parameter in the beforedrop handler, and perform any kind
                // of asynchronous processing such as an Ext.Msg.confirm, or an Ajax request,
                // and complete the drop gesture at some point in the future by calling either the
                // processDrop or cancelDrop methods.
                dropHandlers = {
                    wait : false,
                    processDrop : function () {
                        me.invalidateDrop();
                        me.handleNodeDrop(data, me.overRecord, me.currentPosition);
                        dropHandled = true;
                        me.fireViewEvent('drop', node, data, me.overRecord, me.currentPosition);
                    },
                    
                    cancelDrop : function () {
                        me.invalidateDrop();
                        dropHandled = true;
                    }
                },
                performOperation = false;
                
                if (me.valid) {
                    performOperation = me.fireViewEvent('beforedrop', node, data, me.overRecord, me.currentPosition, dropHandlers);
                    if (dropHandlers.wait) {
                        return;
                    }
                    
                    if (performOperation !== false) {
                        // If either of the drop handlers were called in the event handler, do not do it again.
                        if (!dropHandled) {
                            dropHandlers.processDrop();
                        }
                    }
                }
                return performOperation;
            }
        });

Thanks annette and timriedel! I couldn't get to the ticket since I don't have premium, but timriedel's solution worked. Everywhere I seemed to put it just did not work at all.
