When i try to add a Normativa to the user Hibernate doens't perform any insert in db. Why?

the code is:

HibernateUtil.beginTransaction();
Sesssion session = HibernateUtil.getSession();
session.lock(utente, LockMode.NONE);
utente.getNormativeSegnate().add(normativa);
...
HibernateUtil.commit();
HibernateUtil.closeSession();

inverse=false

thank you. I have inverse="false" now, cascade="all", but when i remove an "normativa" from "utente" with

utente.getNormativeSegnate().remove(normativa);

the sql is like
delete from utente_normative_pref where idutente=?

instead of

delete from utente_normative_pref where idutente=? and normativa_id=?

cascade="all" doesn't make sense for many-to-many.

with save-update the problem is the same.
