> @Entity
> public class Department {
>     @Id 
>     private int id;
>     
>     @Version
>     @GeneratedValue(strategy=GenerationType.AUTO)
>     private int myVersion;
>     
>     private String name;
> }
> A record is inserted... 
> 		Department d = new Department();
> 		d.setName("SALES");
> 		em.getTransaction().begin();
> 		em.persist(d);
> 		em.getTransaction().commit();
> 		em.close();
> ...and queried. 
> If the select is over the entity, "SELECT d from Department d", the version field is
set up  correctly in the returned entity.
> But if the version field is explicitly projected, "SELECT d.id, d.myVersion, d.name from
Department d", the id and the name values are returned fine, but the myVersion value is null.
