Nikita Timofeev closed CAY-2458.
--------------------------------
Resolution: Not A Problem
Assignee: Nikita Timofeev
Cayenne unlike DB has bi-directional relationships. DB only have FK concept so
we can't delete anything in DB when to-many part of relationship is removed.
> Migrate DB Schema: Generated SQL is empty in some cases
