hi ... again :-( it is really frustratingly... i turned OTM->true made: customer.setCar(car) broker.store(customer);
but same... customer is in DB, car not! :-( i have read in aritcle in german-javamag on OJB there was said "all is nice" or am i to stuid? i though it would be possible to store "customer" and his car... has anyone a "runnig"-case for an idot, like me? thanks! --- Brian McCallister <[EMAIL PROTECTED]> schrieb: > Objects are not automatically stored by reachability > -- the car isn't > inserted because it is attached to Customer.
