Completely, I agree with you. Moreover, in my example, when you create a new
session, you have to reattach the main object (employee) and its dependencies
(company). So, if you want to update the "employee", you should do:
---------------------------------------------------
Session session = HibernateFactory.getCurrentSession();
Employee employee = session.load(getEmployeeId());
Company company = session.load(getCompanyId());
employee.setCompany(company);
session.save(employee); // I'm not sure of the syntax.

What is your opinion about it Markus ?
