howard kelsey created OPENJPA-2343:
--------------------------------------
Summary: Version field of related entity returns null when
explicitly projected 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
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.
