Rick Curtis updated OPENJPA-2343: --------------------------------- Summary: Version field returns null when explicity projected from a JOIN in SELECT clause (was: Version field of related entity returns null when explicitly projected in SELECT clause) > Version field returns null when explicity projected from a JOIN in SELECT > clause > -------------------------------------------------------------------------------- > > Key: OPENJPA-2343 > URL: https://issues.apache.org/jira/browse/OPENJPA-2343 > Project: OpenJPA > Issue Type: Bug > Components: query > Affects Versions: 2.2.1 > Reporter: howard kelsey > Assignee: Rick Curtis > Attachments: OPENJPA-2343-2.2.1.x.patch > > > With these entities: > @Entity > public class Foo { > private int id; > private int version; > @Id > public int getId() { > return id; > } > public void setId(int id) { > this.id = id; > } > public void setVersion(int version) { > this.version = version; > } > @Version > public int getVersion() { > return this.version; > } > } > @Entity > public class Bar{ > private int id; > private Foo foo; > @Id > public int getId() { > return id; > } > public void setId(int id) { > this.id = 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. -- This message is automatically generated by JIRA.
