[Dev] Contact quandary

I've been trying to get Contacts created that can be deleted, and I'm
When I create a new Contact with homeSection or workSection set, things
look fine. But when I try to delete the new Contact, I run into
trouble. I filed bug 1351 for this, thinking it's a repository problem,
but now that I've pulled my hair out a little more and looked at the
schema more carefully, I wonder if there's a problem there.
If you look at
you'll see that homeSection and workSection don't have direct
inverseAttributes. They do have sections as a superAttribute, but I'm
not sure this works. Try this thought experiment:
Create a Contact contact.
Create a ContactSection section.
At this point the bi-directional link between contact and section has
contact.homeSection pointing to section.sectionOwner. But
section.sectionOwner is pointing at contact.sections, not back at
contact.homeSection, and in fact attributes may not exist.
Is this a problem, or am I misunderstanding how bi-directional links work?
Interestingly, when I do this in python, the repository doesn't complain
about creating or committing contact.homeSection, but it fails whenever
I try to delete contact. That seemed to me to be because of this
The remedy to this, I thought, would be to create homeSectionFor and
workSectionFor in ContactSection, and change homeSection and workSection
to have these attributes as their inverseAttributes. That seemed to
work, but delete still doesn't quite work, so I don't know what's going on.
