I used Ext.ux.DataView.DragSelector to drag and multiselect my data view. When a scrollbar appear in the data view i cant select items while scrolling or dragging. So i cant select a area from the top of data view to some item in the scrolling area. I used as mention in http://docs.sencha.com/ext-js/4-0/#!...data-view.html. I downloaded the example and increase the number of items. Then the same issue arise to the example too.
