Description

Cayenne Modeler should issue a warning when you have the To-Many checkbox checked on both sides of a relationship in the DbEntity section. When the checkbox is selected on both sides, which isn't a valid combination, Cayenne gets confused and can insert NULLs for FKs and orphan records.

Also, Cayenne Modeler should issue a warning when both sides of the relationship are to-one (assuming To-Dependent PK isn't checked).
