Hello people,
Having a problem with Hibernate, and i can't figure it out. Please help...

Explanation : this exception is thrown when i am trying to delete an entity from a list.
Hierarchy is as follows :
Main entity i am calling Session.saveOrUpdate upon is called OperatoriInterni. This entity has a set of entities of type LocatiiOperatori - these are the ones i am trying to delete : i remove one LocatiiOperatori from the set, and then call saveOrUpdate upon OperatoriInterni. Strangely, problem doesn't appear on the removal of LocatiiOperatori entity, but rather on a child of LocatiiOperator (each LocatiiOperator has one Contacte - this is the entity involved in the exception above)
My mappings are as follows :
Class OperatoriInterni :
Code:
@OneToMany(cascade=CascadeType.ALL, fetch=FetchType.EAGER, mappedBy="operatoriInterni")
@Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.DELETE_ORPHAN})
public Set<LocatiiOperator> getLocatiiOperators() {
return this.locatiiOperators;
}
Class LocatiiOperator :
Code:
@ManyToOne(fetch=FetchType.EAGER, cascade=CascadeType.ALL)
@JoinColumn(name="CONTACTE_ID", nullable=false)
@Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.DELETE_ORPHAN})
callind code :
Code:
public static void salveazaObiect(Object o) throws HibernateException {
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
try {
session.saveOrUpdate(o);
session.getTransaction().commit();
} catch (HibernateException ex) {
session.getTransaction().rollback();
throw ex;
}
}
.............
ServiceGeneral.salveazaObiect(operatorIntern);
.............
Does anyone have any idea on what i may be doing wrong here ? I am just trying to delete something, this should work...
Found something similar here :
viewtopic.php?p=2387041...but this doesn't seem to help.
Any opinion is appreciated :)
