Working with JBOSS4.2 + JPA

Hey,

Lest assume the following:

Person has onetoone (cascade=remove) with Address
GirlFriend has onetoone (there is no cascade) with Address

i want that when i delete person it will delete address and nullify all element that refering to this address.

i add a predelete callback on adress and try to nullfy the refering element, but i get exception - flush during cascade is dangeroues, what can i do?

Thank you
