Hi,

i am getting this exception:

org.springframework.orm.jpa.JpaSystemException: No state snapshot is
available for instance of type "de.logentis.bwh.model.Payment", but
this instance uses state-comparison for dirty detection.; nested
exception is <openjpa-1.1.0-r422266:657916 fatal general error>
org.apache.openjpa.persistence.PersistenceException...

Here are the relevant pieces of the casses:

@Entity
@Table(name = "orders")
@VersionColumn(name = "_version")
public class Order {
...
  @Embedded
  Payment payment;
}

@Embeddable
public class Payment {

  @Basic
  @Enumerated(EnumType.STRING)
  @Column(name = "paymenttype")
  PaymentType type;

  @Column(name = "currency")
  String currency;

  @Column(name = "pricing")
  String pricing;

  @Column(name = "cost")
  int cost;
}

The point is, persisting is no problem at all, the exception will be
thrown by issueing:

Query query = getEntityManager().createQuery("select o FROM Order o");
query.getResultList();

What have i made wrong here? Looked in the docs and everything seems
like expected....
