Description Caspar D. CLA 2010-05-10 02:20:20 EDT 
If one detaches an object and reattaches it, with no
savepoint in between, then rolls the tx back, undoing both the
reattachment and the detachment, the net effect should be no
change. But actually after the rollback the object that was
detached/reattached will no longer be present in the views
"objects" collection.

Requesting it on the basis of its CDOID will produce it in
the correct state, but it'll be a new instance which will
newly be added to the objects collection, not the instance
that was originally detached-then-reattached.

I have a test and a patch for this, but currently I can't
SSH to the CVS server, so I can't do a CVS diff.

To be continued.
