    Tree and Drag and Drop

    amers Level 1
      I have a small question on the Drag and Drop using the Tree component.

      private function dragEnterHandlerTree(event:DragEvent):void {

      var dropTarget:UIComponent = UIComponent(event.currentTarget);

      if (event.dragSource.hasFormat('treeItems'))


      // Signal that this data can be dropped onto the target


      trace("drag accepted.");

      var dragItems:Array = event.dragSource.dataForFormat("treeItems");

      now dragItems is an Array, it has the length of 1; but when I look at the information through a trace, it's empty.

      Any ideas on how to get the node's information? I've tried a couple different ways, one way had an issue and it read the tree node to be:

      <label="name" id="data" anotherID="id">

      any ideas?

          The data is an XML object, so tracing it directly, as in trace(dragItems[0]), will output an empty string since the node doesn't have any content. You can trace dragItems[0].toXMLString() to get the full XML. And since it's an XML object, just use e4x operations to get at the data.

            thanks muchly!

            I was finally able to get the information and showing the XML helped quite a bit.

            trace("name: " + dragItems .@name);
            trace("ID: " + dragItems

            After I got the information, I was able to successfully update the information using a web service. Now I'm having some issues on how to refresh the datagrid (since it's in it's own component).

            thanks again!
