Kevin Menard commented on CAY-436:
----------------------------------
All in all, this looks pretty good. A couple questions:
1) In DbLoaderHelper, is there any reason that you need to explicitly update
the ObjEntity? Or rather, is there a reason that your observer pattern fails
to work here?
2) Is there a reason that the observer pattern fails in
ObjRelationshipInfoModel#savePath?
I may be looking at the code wrong, but it strikes me that the
EntityMergeListener or something similar could be used in such a way that you
don't actually have to hook in explicit updates in so many places.

> Should be good to change default delete rules for object relationships, one
> to many - cascade, and vice versa - to nullify. I think it's the rules used
> mostly for these relationships.
> And the best thing would be to have configurable options for these, but
> that's more complex.
