UnsupportedOperationException with StatelessSession --------------------------------------------------- Key: HHH-3482 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3482 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.0.GA Environment: Linux, Hsql Reporter: Adrien Attachments: timestampStateless.zip When using a StatelessSession and saving a ManyToOne, we have an UnsupportedOperationException because of a call to getTimestamp() on the StatelessSession. May be the AbstractEntityPersister.isTransient() should always return null when dealing with a StatelessSession, since everything is transient in this case. StatelessSession s = getSessions().openStatelessSession(); s.beginTransaction(); Person p = new Person( new Long(1), "steve", 123 ); s.insert(p); Order o = new Order( new Long(1), p ); s.insert(o); // --> UnsupportedOperationException java.lang.UnsupportedOperationException at org.hibernate.impl.StatelessSessionImpl.getTimestamp(StatelessSessionImpl.java:435) at org.hibernate.persister.entity.AbstractEntityPersister.isTransient(AbstractEntityPersister.java:3422) at org.hibernate.engine.ForeignKeys.isTransient(ForeignKeys.java:204) at org.hibernate.engine.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:241) at org.hibernate.type.EntityType.getIdentifier(EntityType.java:430) at org.hibernate.type.ManyToOneType.nullSafeSet(ManyToOneType.java:102) at org.hibernate.persister.entity.AbstractEntityPersister.dehydrate(AbstractEntityPersister.java:2045) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2291) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2708) at org.hibernate.impl.StatelessSessionImpl.insert(StatelessSessionImpl.java:117) at org.hibernate.impl.StatelessSessionImpl.insert(StatelessSessionImpl.java:99) at org.hibernate.test.timestampStateless.TimeStampProbTest.testTimeStampTest(TimeStampProbTest.java:28) You may see the joined test case. I found a old post on the forum with the same problem : http://forum.hibernate.org/viewtopic.php?p=2304937&sid=03c689ec5b12ee... I hope this will help. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
