No state snapshot is available on @Embedded class when using runtime
enhancement via spring-tomcat-weaver
----------------------------------------------------------------------------------------------------------
Key: OPENJPA-659
URL: https://issues.apache.org/jira/browse/OPENJPA-659
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 1.1.0
Environment: Tomcat6, Java6, Mac OS X, Spring 2.5
Reporter: Marc Logemann
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();
