IndexOutOfBoundsException on drop in case of multipleSelection

[GoogleCodeExporter]

GWT version 2.0.3
GWT-DnD 3.0.1

Steps to reproduce the problem:
1. multipleSelectionAllowed is true for the used drag controller 
(PickupDragController)
2. the drop controller is extended from AbstractInsertPanelDropController
3. the drop panel (bound to the drop controller is extended from 
ComplexPanel
4. the drop panel contains N widgets and all of them are registered as 
draggable (the same drag controller)
5. in a drag operation, all N widgets are selected and than dropped just 
before the last widget within the panel
6. the drop panel throws IndexOutOfBoundsException from method 
checkIndexBoundsForInsertion() because
    AbstractInsertPanelDropController.onDrop() tries to insert a widget 
on an invalid index (grater than the current widget count)

As a quick work-around I overrided the insert() method of the drop panel in 
the following way:

@Override
protected void insert(Widget child, com.google.gwt.user.client.Element 
container, int beforeIndex, boolean domInsert) {
  if ( beforeIndex <= this.getWidgetCount() ) {
  super.insert(child, container, beforeIndex, domInsert);
  } else {
    super.add(child, container);
  }
  ...
}

But I think the real solution would be to correct the behavour of 
AbstractInsertPanelDropController.onDrop().

I place this workaround in public domain.

Appears to have been fixed. I was unable to reproduce using
