Re: Resetting an object back to committed state (including relationships)

Hmm, so here's the situation I'm seeing.

Personalization ->> Image

Phase 1:
I remove an Image and add new one.

Phase 2 (later down the line, but within the same OC):
I decide that I don't want to make those changes to the original
Personalization, but rather in a new one...so I duplicate the
Personalization and its Images (as it currently is), and then want to reset
the original Personalization back to it's saved state.  So I call
invalidateobjects on the Images and then the Personalization created in
Phase 1.  This will save, but it will still execute the original delete of
the Image in Phase 1 and the insert of the new Image from Phase 1.  So I
end up modifying the objects from Phase 1, even though from an object
perspective they are in the correct state.  The OC never knew to undo its
delete/insert, so those proceed anyway.

Thoughts?
