Using NHibernate version 1.0.0.0

We are using nhibernate in an ASP.net 2.0 project and are have some issues.

We have noticed that when we the “BuildSessionFactory” method is called on our cfg.configuration object that nhibernate creates instances of several of our entity types. There does not seem to be anything unique out the entity objects it is instantiating (it ties to create the same 7 objs every time – we have 150 entity types total).

Creation of these entity types has become a problem because recently we have implemented role based security in the constructors of all entity types. What sometimes happens is the user who is accessing the site sometimes does not have permission to access a certain type which crashes the application.

What we need to know is why the call to “BuildSessionFactory” is creating instances of these types and how can we prevent it from doing so.

Additionally if anyone else has encountered this and has a workaround please post it here.

It creates the objects and reads the value of their identifier and version properties to guess the unsaved-value for them. If you set unsaved-values manually in the mapping files the objects will not be created.

I have run into the same problem and It was missing unsaved-value tag in my xml mapping file
