Version field returns null when explicitly projected in SELECT clause
---------------------------------------------------------------------
Key: OPENJPA-662
URL:
https://issues.apache.org/jira/browse/OPENJPA-662 Project: OpenJPA
Issue Type: Bug
Components: query
Reporter: Dinkar Rao
Priority: Minor
With this entity:
An entity has a version field, with AUTO strategy.
@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.
