What determines would deleted records be updated first (1-* mapping)?

Question

Suppose that we have 1 to many between A and B, and that we delete row in B (B is many side). B is privatelly owned and ValueHolder indirection.
Now, I am seeing that if I do delete a row from B, it will be first updated (with the foreign key set to null), and then deleted.
This is relativelly recent development - we did not change mapping file database or any toplink setting we were aware of. Concern is why this started happening all of the sudden, while previously TopLink would detect that row would eventually be deleted and skip update altoghether?
Could anybody point to any guidelines under which circumstences would update be done on the deleted row first, as opposed to update being skipped if the row is eventually going to be deleted?
TopLink 10.1.3.1, Oracle 10.2.0.1.0, JDBC driver 10.2.0.1.0
Thanks!

Answer 1

Doug,
This is somewhat complex setup, I would try to get it as simple as possible but would not remove anything from the tables (just in case it is related to problem).
So, WorkspaceConfig and TestCaseType are in 1:M. TestCaseType foreign key for WorkspaceConfig is NOT NULL constrained. TopLink would on delete of the TestCaseType object
generate UPDATE for TestCaseType that is going to break not null constraint on foreign key.
This is exception that we get:
