Ok got my interceptor working, bit raw convert from the Hibernate one
I found but does what I wan't it to now, selects the version back from
the DB and does it correctly how I would like it to, thoughts?
public override bool OnFlushDirty(object entity, object id, object[]
currentState, object[] previousState, string[] propertyNames,
NHibernate.Type.IType[] types) {
ISessionImplementor sessimpl = _session.GetSessionImplementation();
IEntityPersister persister = sessimpl.GetEntityPersister(entity);
EntityMode mode = _session.GetSessionImplementation().EntityMode;
if(persister.IsVersioned) {
object version = persister.GetVersion(entity, mode);
object currentVersion =
persister.GetCurrentVersion(id, sessimpl);
if (!persister.VersionType.IsEqual(currentVersion, version))
throw new
StaleObjectStateException(persister.EntityName, id);
}
return base.OnFlushDirty(entity, id, currentState,
previousState, propertyNames, types);
}
