Criteria.createAlias : QueryException on @Embedded attributes
-------------------------------------------------------------
Key: HHH-4587
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4587
Project: Hibernate Core
Issue Type: Bug
Components: annotations, core, query-criteria
Affects Versions: 3.3.0.GA
Environment: Hibernate 3.3.0
MySql 5.1.29
Reporter: Marcos Antonio de Vasconcelos Junior
Priority: Blocker
Hi, recently i discover my app always throws a Exception when searching with alias in
@Embedded fields.
The model look like this.
[code]
@Embeddable
public class Contato {
//attrs
}
@Table
@Entity(name = "motorista")
public class Motorista {
@Embedded
private Contato contato;
//+attrs
}
[/code]
And the following code:
[code]
Session s = HibernateUtil.openSession();
Criteria crit = s.createCriteria(Motorista.class);
crit.createAlias("contato", "contato");
crit.add(Restrictions.like("contato.nome", "jo",
MatchMode.ANYWHERE));
System.out.println(crit.list().size());
[/code]
Always throws QueryException and the StackTrace:
[code]
Exception in thread "main" org.hibernate.QueryException: could not resolve

When looking for a solution i discover this problem don't occurs when I use the
@OneToMany + @JoinColumn annotations instead of @Embedded.
No one in hibernate forums and in a brazilian forum I'm member can't help, so I
think it's a bug.
