Session Is closed in Session per WCF call scenario

Question

I have a problem. I've setup ma session management as per wcf call. I am using StructureMap as IoC and I am injecting the session to the repository constructor.

there is one scenario when I am getting Session is closed exception. So I debug and this is the workflow: 1. SessionFactory.OpenSession() 2. Save Session in context 3. StructureMap gets the session from context (For().Use<_sessionFactory.GetCurrentSession()), and inject the session into my repository (at this moment Session.IsOpen == true) 4. I am doing some query. 5. On query execute (the exception Session Is closed is thrown) 6. WchCall ends 7. The Detach(InstanceContext) from NHibernateContextManager:IExtension is called (at this momment Session.IsOpen == true!!!!) 8. Session.Close is called

This exception happens only in one scenario, everything else is working ok.

Please help.

And this happens only in one class, the same repository works in another one. — Luka
And this only happens if I let StructureMap instantiate the class, but if I uset ObjectFactory.GetInstance<T>() then it works ok. — Luka

Ok, found the problem. The problem was in StructureMap conviguration for this class: I had: ForSingletonOf().Use();

Now changed to: For().Use();
