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....
