NHibernate.JetDriver Not Working at all in 1.2.0.Beta2 (encounters System.NullReferenceException)
-------------------------------------------------------------------------------------------------

         Key: NH-818
         URL: http://jira.nhibernate.org/browse/NH-818
     Project: NHibernate
        Type: Bug
  Components: Core  
    Versions: 1.2.0.Beta2    
    Reporter: Simon


Using simple test case (from ForumQuestions of NHibernate.Examples, changing driver to JetDriver)

ISession session = sessions.OpenSession();
OfferType offerType = new OfferType();
offerType.Key = 1;
offerType.Description = "somevalue";
session.Save(offerType);
