CDOSetFeatureDelta.getOldValue is always UNSPECIFIED [message #653938]

When I have an CDOObject commited to a repository, say "foo" and I do something like:

foo.setName("foo");
commitInfo = trans.commit()
foo.setName("bar");
commitInfo2 = trans.commit();

I correctly get a CDOSetFeatureDelta back in commitInfo2 corresponding to "name" being set to "bar". However, I always seem to get the "UNSPECIFIED" object for the oldValue rather than "foo", which is what I would have expected.

Does anyone have any idea why this might be happening?

We've never put much effort in remembering *local* oldValues in the CDOFeatureDeltas because they're not transfered to the server or other clients anyway. But you're right in that it looks inconsistent from a CDO API user's point of view. I think we've fixed this in https://bugs.eclipse.org/bugs/show_bug.cgi?id=336729
