1) the title are talking about Timestamp but you are using <version> 2) that mapping is not using MsSQL timestamp but a int version 3) the unsaved value cant be string empty
4) if you need help, please try to send something real Thanks. 2009/12/1 sebring <[email protected]> > > > I have an entity mapped in NHibernate with optimistic concurrency > control using a SQL timestamp column as the version number.
