??? Are you referencing an illustration you tried to attach? If so,
it didn't make it. :-) I don't think attachments are allowed on the
list. Do you have a URL to a shared copy?

This is just a guess (since I have no idea to what you're
referring), but pehraps you haven't defined both sides of the
relationship and / or specified one as the inverse to the other.
In other words:
Parent (children->) <------>> (<-parent) Child
You have to specify the "children" relationship as pointing to
(to-many) Child, then specify the "parent" relationship as pointing to
the parent. On either one of those relationships, specify the opposite
as the "Inverse" relationship.
Hope this helps.
