Life-saving work guys, hope one of you could help > with this question. > > SETUP: > I'm building an MVC web application using NHibernate 2.0.1.4000 as my > business tier. The app implements a UnitOfWork which wraps around an > ISession. The ISession itself is produced by an ISessionFactory > (based of the ORMs of course) then stored to the HttpContext to be > used globally throughout the application. In each Repository Class, a > Lambda expression is passed to a Find<>() method of the UnitOfWork > (via its ISession field) in order to perform queries against the DB > using session.Linq<>() (Love NHibernate.Linq, VERY AWESOME!). In the > ORMs, the id elements contain generator class="identity" and the PKs > are Int32... FlushMode = Never, unsaved-value="0". > > > PROBLEM: > When I want to build a transaction: I use the UnitOfWork to call > BeginTransaction(), I create a transient instance of an object (new > object) and populate its properties, I use the UnitOfWork to > SaveOrUpdate() the newly created object to the current session.
