    Default Unanswered: setting draggable config to Ext.util.ComponentDraggable

    Does the delegate on the Ext.util.ComponentDraggable need to be defined? Looking at the docs, it seems like it's optional, but when I use it instead of just marking the draggable field to "true", I get a TypeError when dragging.
    Code:
    Uncaught TypeError: Cannot read property 'dom' of undefined
    Code:
       var panel = Ext.create('Ext.tree.Panel', {
         title: 'Task',
         draggable: new Ext.util.ComponentDragger(this, {
    				//delegate : 'foo', omitted, draggable: true lets me use the panel's titlebar
    				onStart: function() {
    					console.log('Start Drag');
    				}
    			}),
    Or is there some way I could just set the panel draggable attribute to "true" and get the ComponentDragger after panel creation to add events to its config? Thanks.

    The ComponentDragger's first argument is the drag target which needs to be the element that is used to drag which you won't have at component instantiation.
