AssertionFailedException with DND of binary type [message #203033]

I am trying to drag a binary type from a library in the package explorer
onto my GEF diagram.

When I do that I get the exception below because a DROP_MOVE (instead of a
DROP_COPY) was initiated. So when I hold down the shift key while dragging,
everthing works fine. But I don't want to hold down the shift key all the
time (move doesn't make sense for a binary type from a jar anyway).

Does anybody know what to do? Am I asking in the right forum?

Actually I lied, I always get this exception. But when I hold down the shift
key, my AbstractTransferDropTargetListener actually tries to create the
command.

Just FYI: I was able to get it to work by setting

getCurrentEvent().detail = DND.DROP_COPY

in org.eclipse.gef.dnd.AbstractTransferDropTargetListener.handl eDrop() and
handleDragOver().
