Deleted collection still exist

I'm trying to delete a collection of objects, but somehow they still remain.

List<Assignment> assignments = shift.getAssignments();
shift.getObjectContext().deleteObjects(assignments);
shift.getObjectContext().commitChanges();

After commitChanges executed, the only assignment in the collection has this value: 

[{<ObjectId:Assignment, assignment_id=26067>; committed; // snipped for clarity

I thought that after deleteObject(), the state would be DELETED; and after commitChanges(), it should not remain in the collection. According to this: http://cayenne.apache.org/docs/3.0/persistent-object-lifecycle.html.

What am I missing?

EDIT: changed the code to remove a different data object which in turn propagate changes to the assignments.

If you want the objects to be removed from collection on delete you can do one of the two things:

  • Manually remove them by iterating over a collection copy and calling "removeFromAssignments()"
  • Define a NULLIFY delete rule for the assignment -> shift relationship
