wpf-DragDrop in a listbox with groupstyle

Question

I am using the control library from http://code.google.com/p/gong-wpf-dragdrop/successfully for my listbox dragging operation.But there is an issue when i drop an item to a listbox with a group style.I have traced that in the DropInfo class the line

UiElement item=itemscontrol.GetItemContainerAt(e.GetPosition(itemscontrol));

always returns a null. My listbox is bound to a CollectionViewSource.

Any inputs will be highly appreciated.
