Alias does not get initialized..
@Entity
public class Foo {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public Long id;
@Basic
public Key bar;
@OneToOne(fetch = FetchType.LAZY)
@Column(name = "bar", insertable = false, updatable = false)
public Bar barAlias;
}
@Entity
public class Bar {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public Key key;
@Basic
public String name;
}
public class UnOwnedRelationshipTest extends BaseDataStoreTest {
public void testRelation() throws EntityNotFoundException {
Bar bar = new Bar();
beginTx();
getEntityManager().persist(bar);
commitTx();
beginTx();
Foo pojo = new Foo();
pojo.bar = bar.key;
getEntityManager().persist(pojo);
commitTx();
pojo = getEntityManager().find(Foo.class, pojo.id);
com.google.appengine.api.datastore.Entity e = DatastoreServiceFactory
.getDatastoreService().get(KeyFactory.createKey("Foo", pojo.id));
assertTrue(e.hasProperty("bar"));
//this fails
assertNotNull(pojo.barAlias);
}
}
The test fails, alias is not initialized..
It does not work even when I use getters/setters to access alias, Neither it
works for @oneToMany as you explained in example.
I use GAE SDK 1.3.2
When using joins, From Foo result returned, can I do
foor.getBarAlias().getName() !??
