> With these entities:

> private int id;
> private int version;
> @Id

> @Entity
> public class Bar{
> private int id;
> private Foo foo;
> @Id
> public int getId() {

> public void setId(int id) {

> }
> public void setFoo(Foo foo) {
> this.foo = foo;
> }
> @ManyToOne
> public Foo getFoo() {
> return foo;
> }
> }
> Insert a record for each associating foo with bar.
> Foo foo = new Foo();
> em.getTransaction().begin();
> em.persist(foo);
> Bar bar = new Bar();
> bar.setFoo(foo);
> em.persist(bar);
> em.getTransaction().commit();
> em.close();
> queries
> select bar.id as id, foo as foo from Bar bar join bar.foo foo
> The version field is available via foo.getVersion()
> select bar.id as id, foo.version as version from Bar bar join bar.foo foo
> version is always null.
> By enabling the jdbc debug I can see that the actual SQL being run is correct
> but the value is just not hydrated.
