[bpel-dev] Undo for namespaces change

["Dennis Ushakov" <dennis.ushakov@xxxxxxxxx>]

Hi!

I'm currently working on making namespaces support in BPEL Editor
correct. Currently version in repository is working correctly only
with "bpws" prefix for BPEL elements. I've fixed this problem and some
others regarding creation of elements with correct namespace prefix.
But I've got one issue left.
If I edit namespace prefix or url in source tab I can easily undo my
changes in the source tab. But to be able to undo these changes from
design view I need to add undo command to design view command stack.
It seems to me that UpdateModel cannot be used because EMF-object
doesn't notify about namespace change. It simply has no such feature.
Could you give me a clue how should such a command be implemented? Or
is it better to introduce some feature to notify recorder about
namespace changes?

Thanks,
Dennis
