Extjs4.2 Desktop icons Drag white screen to resolve

The last time I did a extjs4.2 desktop demo, the desktop from the original package stripped out, and realized the table icon to change columns, desktop icon drag, but users reflect the desktop icon drag will appear white screen, tested, in This problem exists in both extjs4.2 and Extjs5.0,

After repeated tracking debugging, found that their own added code is not a problem, the problem is in the ExtJS of the custom class, in the extjs4.1 of the Ext.define (' Ext.dd.DragZone ' ... is defined in the

    Afterrepair:function () {        var me = this;        if (Ext.enablefx) {            ext.fly (Me.dragData.ddel). Highlight (Me.repairhighlightcolor);        }        Me.dragging = false;    },

This code, is to handle the subsequent work after dragging, and in the extjs4.2 ' Ext.dd.DragZone definition, for some reason, without this code, as long as the code, the problem will no longer appear, a day, the perfect solution, in fact, the problem is not complex, but to find the problem more difficult.

Extjs5.0 the same problem, should be the same reason, but not tested.
