I am actually trying to drag an object from one common navigator and
drop it onto another common navigator.
I thought at the drag side, we need to get hold of the drag object and
have a reference to it on the drop side. Hence i added the dragAssistant
and dropAssitant.
So as per your reply, if i understand correctly, i just need to add a
dropAssistant at the receiving side and handle the drop?

Yes, that's all you should need. And if you are using resources, then
you don't even need that.

Great. This is awesome.
It works fine. Thanks very much Francis.
Guess the SWT DND tutorial took me on the wrong path and confused me.
I now can handle DnD in my views.
