| Re: [bpel-dev] Undo for namespaces change |
Hi Dennis,
mmh, the problem here is that EMF EObject, unlike DOM nodes, do not carry
around the namespaces. Therefore, this can be changed on a DOM level, but
since that change wouldnt be visible in the rgaphical BPEL, EMF doesn't
care. Only the BPEL writer cares. This is a tricky question actually.
Why would we want that (== change of a namespace prefix) to have effects in
the graphical view anyway ? Is there any reason for that (I am asking that
stupid because I don't see any reason) ?
Cheers
Simon
ps..: By the way, I found yesterday that when you create a process that has
a structued activity (lets say a sequence, and then a while in that
sequence, and then a something else in the while), and you save and close
everything is fine. But once you reopen the process, then the inner
activities are lost (at least in the graphical view). To me this might be
caused by the DOM Facading work - did anyone of you ever notice that ? Or
is this just happening on my machine ?

Subject: [bpel-dev] Undo for namespaces change
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
