Will Dazey created OPENJPA-2874:
-----------------------------------
Summary: Embeddable objects are not updated and orphaned
references removed
Key: OPENJPA-2874
URL: https://issues.apache.org/jira/browse/OPENJPA-2874
Project: OpenJPA
Issue Type: Bug
Components: jpa
Affects Versions: 2.2.2
Reporter: Will Dazey
Very similar to https://github.com/hibernate/hibernate-orm/pull/3817. Tested on
2.2.2 and I could not find an existing bug that fixed this already.
Entities:
```
@Entity
public class RaceDriver {
@Id private Integer id;
@Embedded private Car car;
private String name;
}
@Embeddable
public class Car {
@Id private Integer id;
@OneToOne(orphanRemoval = true, fetch = FetchType.LAZY)
private Engine engine;
@Column private String color;
}
@Entity
public class Engine {
@Id private Integer id;
private Integer horsePower;
}
```
Test:
```
em.getTransaction().begin();
final Engine engine = new Engine( 1, 275 );
final Car car = new Car(1, engine, "red");
final RaceDriver raceDriver = new RaceDriver(1, "Bob", car);
em.persist( engine );
em.persist( raceDriver );
em.getTransaction().commit();
em.clear();
em.getTransaction().begin();
final RaceDriver raceDriverFind = em.find( RaceDriver.class, 1);
final Car carFind = raceDriverFind.getCar();
//check, that at the moment the engine exists
Assert.assertNotNull(carFind.getEngine());
//update parent entity
raceDriverFind.setName("Ted");
//update the embeddable
car.setColor("green");
//orphan the engine object
car.setEngine( null );
em.getTransaction().commit();
```
Trace:
```
UPDATE RaceDriver SET name = ? WHERE id = ?
[params=(String) Ted, (int) 1]
```
The issue is that OpenJPA is not updating the embeddable values on transaction
commit. Also, OpenJPA is not removing the orphaned Engine reference.
