Hi,
Sorry for the long email on this one.
I declared an embeddable entity:
@Embeddable
public class OwnerInfo implements Serializable {
@Enumerated(EnumType.STRING)
protected OwnerScope scope;
.....
}
and used it in a another entity:
@MappedSuperclass
public abstract class AbstractModel implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE)
protected Long id;
@Version
protected Integer optLock;
....
}
@Entity
@Table(name = "question")
public class QuestionModel extends AbstractModel {
@Embedded
protected OwnerInfo ownerInfo = new OwnerInfo();
....
}
Everything worked fine when using property access, when I switched to
using field access (above) I got the following exception:
org.springframework.transaction.UnexpectedRollbackException: JPA
transaction unexpectedly rolled back (maybe marked rollback-only after a
failed operation); nested exception is

Could anyone tell me what I'm doing wrong? Let me know if anyone needs
more details.
Thanks in advance.

Adrian Co
PS: When I added an @Id field to the OwnerInfo class, the exception
disappeared. I don't know why and I don't think its the right fix. :)
