Hi Thomas, Thanks a lot [actually I could imagine better place where to inform about such important thing than comparison of PB and ODMG API in faq.html :)].
are you volunteering to improve the docs? all help is welcome!
I have probably similar problem. Don't you know if it is the same problem? I have 1:n association between classes A and B. I do the following: 1) I find one instance of A 2) I find n instances of B 3) I set collection of instances of class B to instance of A. 4) I store instance of A. There are no updates on the table corresponding to class B (foreign key should be changed!).
OJB provides automatic propagation of foreign keys. But it does only work if the foreign key attributes of the B instance are set to 0 or null.
(This is done to avoid data corruption)
If you are loading B instances that already have a FK filled with a non-zero or non-null value, you have to set the FK attributes explicitely!
cheers,
Thomas

You have to delete the address explicitely.

Inserting and updating addresses is working correctly. Don't you have any patch?
