[flexcoders] DataGrid's Drag and Drop stops working after user clicks on column header.

[Mark Lapasa]

Hello all,

If you cut & paste the following:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application
    xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute"
    creationComplete="creationCompleteHandler()">
    <mx:Script>
        <![CDATA[
            import mx.collections.ArrayCollection;
           
            [Bindable]
            private var ac:ArrayCollection;
           
            public function creationCompleteHandler():void
            {           
                ac = new ArrayCollection([    {label:"First", rank:1},
                                            {label:"Second", rank:2},
                                            {label:"Third", rank:3}]);

                dg.dataProvider = ac;
            }

        ]]>
    </mx:Script>
    <mx:DataGrid id="dg"
        dragEnabled="true" dropEnabled="true"
        dragMoveEnabled="true">
    </mx:DataGrid>   
</mx:Application>




...dragging and dropping to a different order works great. As soon as 
you click on the header, a column sort is applied and then it takes over 
as precedence over any changes the user wants to perform manually by 
doing drag and drop.

Why does drag and drop stop working? What gives?

Thx,
