> 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 property: nome of: br.com.sistram.model.prestador.Motorista

> [/code]
> 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.
