Nhibernate Lazy Load exception after a view exception

Question

I get a weird behavior with NHibernate with Fluent Configuration.

Whenever a generic exception unrelated to the NHibernate occurs i.e. in the view a DivideByZeroEx

Answer 1

As Radim Köhler noted i was saving a lazy-loaded object in Session that caused the problem.

But i wanted to avoid the Serilization of all objects and i fixed it as follows.

I added the following method to eager-load an entity instead of lazy

public T FindByEager(int id)
    {
        T entity = FindBy(id);
        NHibernateUtil.Initialize(entity);
        return entity;
    }

And changed BaseController to

if (Session != null) Session["User"] = userRepository.FindByEager(LoggedUser.Id);
