Tree to grid node dragging working in Ext4.0 but 4.1
===

I've a tree-panel as

    var t = new Ext.TreePanel({
        .
        .
        store: <loaded dynamically>
    	viewConfig: {
    		allowCopy: true,
    		copy: true,
    		plugins:{
    			ptype: 'treeviewdragdrop',
    			dragGroup: 'dragGroup',
    			dragText: 'Place the node to grid'
    		}
    	}
    });


And a grid-panel as

    var bpMappingGrid = Ext.create('Ext.grid.Panel',{
        .
        .
        .
        .
    	columns:[
    	{
    		header:'Application Name',
    		dataIndex:'applicationName', //The same name should be there in treenode too
    		align:'center',
    		width:150
    	},{
    		header:'Tagged BusinessProcess',
    		dataIndex:'businessProcessName', //The same name should be there in treenode too
    		align:'center',
    		width:180
    	}
    	],
    	store: <loaded dynamically>,
    	viewConfig: {
    		plugins:{
    			ptype: 'gridviewdragdrop',
    			dropGroup: 'dragGroup'
    		}
    	}
    });

Every node has an associated `businessProcessName` and `applicationName`. So when we drag a node, it assigns the corresponding values of these data indices to the grid.

**This code works fine in ExtJS 4.0 but its inserting an empty row in the grid in ExtJS 4.1.
Please tell me how to make it working for ExtJS 4.1.**
