I have the following problem

House house = new House();
house.setAddress(addressFromDataBase);

Person person = new Person();
person.setAddress(addressFromDataBase);

person.setHouse(house);

so when I call session.saveOrUpdate(person)

guess what, error:
-> a different object with the same identifier value was already associated with the session

help?

Ow yeah, found it. The solution for all the problems in the world, including war, is called "merge". I got the information from here http://pro-programmers.blogspot.com/200 ... ption.html. I'm quite happy now, I don't need to replicate my Address object.
