Hi Jim
> Are you able to query the audited entities using the AuditReader?
Yes, I can create queries using AuditReader.
Two questions:
1) Are you using current_session_context_class = thread ?
<property name="current_session_context_class">thread</property>
2) Are you using the "real" Hibernate Session.
http://www.mail-archive.com/users@tapestry.apache.org/msg37227.html
Here is my code (the relevant part)
@Inject
private HibernateSessionManager sessionManager;
.....
AuditReader reader = AuditReaderFactory.get(sessionManager.getSession());
AuditQuery query =
reader.createQuery().forRevisionsOfEntity(getClassDescriptor().getType(),
false, true);
query.add(AuditEntity.id().eq(getBeanId()));
Saludos.
Alejandro.
