Description

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();
