[flexcoders] Drag&Drop event propagation

[txakin]

Hi all,

I have a tree component with an xml file as dataprovider.
I would like to move node from one parent to other one, previously an alert 
message.

1.- I drag a node
2.- Before drop this node in new parent node, i want to display an alert 
message.
3.- If the user click YES, i want to move the node to the new parent
4.- If the user click NO, i want to cancel the drag and drop event.

Here is my source:

in the tree component i have the next properties:

dropEnabled="true"
dragEnabled="true"
dragMoveEnabled="true" 
dragDrop="customDragDrop(event)"       
allowMultipleSelection="false"

The customDragDrop(event) function is:

import mx.events.DragEvent;
import mx.managers.DragManager;
            
private var queuedEvent:DragEvent;

private function customDragDrop(event:DragEvent): void
{
  //Get the data from the dragSource
  var items:Object = event.dragSource.dataForFormat("treeItems");
  event.stopPropagation();
  queuedEvent = event as DragEvent;     
                
  var messageText:String = "Are you sure you want to move the node "  
                           + items[...@label.touppercase() + "?";
  var titleText:String = "Warning";
  var alert:Alert = Alert.show(messageText, titleText, 
                               Alert.NO | Alert.YES, 
                               this, customDragDropHandler,alertIcon);
}
            
private function customDragDropHandler(event:CloseEvent):void{
  if (event.detail == Alert.NO){
    queuedEvent.preventDefault();
    queuedEvent.target.hideDropFeedback(queuedEvent);
    DragManager.showFeedback(DragManager.NONE);
  }
  else {
    dispatchEvent(queuedEvent);                         
  }                     
}

I don´t know why i can not get my solution, please i need your help.

Thanks in advance.
