Hello,



I'm working in a project with hibernate + ehcache. I'm trying to override the LOAD method of SingleTableEntityPersister for one concrete object. I want to override it, so as to load the object not only taking into account the ID property but also some other(s).

I've overwritten that method by calling a named query. At first, it seemed to work, but after some executions it throws a stackoverflow exception (see bellow).



@Override
public Object load(Serializable id, Object optionalObject, LockMode lockMode, SessionImplementor session) throws HibernateException {

Query loadingHQL = session.getNamedQuery("namedQueryForLoadingObject");

loadingHQL.setParameter("id", id);

loadingHQL.setParameter("otherField", otherFieldValue);

return loadingHQL.uniqueResult();

}



How should I overwrite this functionallity? Should I take into account some other alternative?



Thanks in advance,



Jessi
