I'm trying to set up an assocition using the hibernate "delete orphan" option. I believe I have all the annotations correct after cross referencing the hibernate book. However after removing the item from the collection, Hibernate is attempting to set the foreign key to null. Which violates a database constraint. Hibernate has been told about the not-null constraint...
Here's my code:
Consuming code (In actuality its a Struts 2 action using preparable and custom type converters, here I've localized all the relevant code and have tests that it gives the same error as my actual architecture. But felt I had to explain the combination of repositoty and direct entityManager access...)
I had thought that the combination of the DELETE_ORPHAN on the owning side of the association and the nullable=false on the owned side would have prevented hibernate from attempting that update. What am I doing wrong?
