OK, so now I've implemented ISessionManager.OpenStatelessSession(). Thanks
to Henry for committing it in the Castle trunk.
Now, I have a new problem with it over DetachedCriteria with the following
error message:
*Unable to cast object of type
'Castle.Facilities.NHibernateIntegration.StatelessSessionDelegate' to type
'NHibernate.Engine.ISessionImplementor'.*
It's reproduced using the following test:
[Test]
public void TestTransactionStatelessUsingDetachedCriteria()
{
RootService service = container.Resolve<RootService>();
string blogName = "Delicious Food!";
var blogA =
service.CreateBlogStatelessUsingDetachedCriteria(blogName);
Assert.IsNotNull(blogA);
var blogB =
service.FindBlogStatelessUsingDetachedCriteria(blogName);
Assert.IsNotNull(blogB);
Assert.AreEqual(blogA.Name, blogB.Name);
}
[Transaction]
public virtual Blog FindBlogStatelessUsingDetachedCriteria(string name)
{
DetachedCriteria dc = DetachedCriteria.For<Blog>();
dc.Add(Property.ForName("Name").Eq(name));
var session = this.SessionManager.OpenStatelessSession();
////return dc.GetExecutableCriteria(((StatelessSessionDelegate)
session).InnerSession).UniqueResult<Blog>();
return dc.GetExecutableCriteria(session).UniqueResult<Blog>();
}
AFAIK, it seems to be related to an old issue with
ISessionManager.OpenSession() which is discussed here:
http://forum.castleproject.org/viewtopic.php?t=2002. As hammett suggested,
to workaround the issue by accessing the ISession directly from
SessionDelegate. So, if I uncommented this line (return
dc.GetExecutableCriteria(((StatelessSessionDelegate)
session).InnerSession).UniqueResult<Blog>();), it would just work.
Actually, I'm confused and wondering how it can work and cannot. Is that
related to NHibernateFacility itself or NHibernate directly?
Thanks.
