I got a class called Rappel and another called RappelPk (both generated by hibernate).
I try this:




findCriteria(Integer atrbFromRappelPk, String atrbFromRappel){

s = HibernateUtil.currentSession();
crit = s.createCriteria(getReferenceClass());

if(atrbFromRappelPk!=null){
crit.add(Expression.eq("codigoExterno", atrbFromRappelPk));
}


if(nombre != null && !nombre.equals("")){
crit.add(Expression.eq("numeroVendedor", atrbFromRappel));
}

retorno = crit.list();
}


With the attribute atrbFromRappel works well, but with the atrbFromRappelPk KO:

net.sf.hibernate.QueryException: could not resolve property: RappelPk.codigoExterno of: com.cofidis.fuentes.gestion.modelo.valueobject.Rappel


I tried the next:

crit.add(Expression.eq("RappelPk.codigoExterno", atrbFromRappelPk));

but it doesn't work, what can I do?

Show us your mapping. It looks as if the property codigoExterno of class RappellPk is not mapped. Do you have getter/setter for this property defined?

I solved It, I must put:

crit.add(Expression.eq("Id.codigoExterno", codeExtern));
and not

crit.add(Expression.eq("codigoExterno", codeExtern));


Thank's.
