My entity object is a proxied object as I'm using Castle Windsor Container with an interceptor. When trying to save this object I get a MappingException.

NHibernate.MappingException: Unknown entity class: IContextProxy21ea5728b30e4035bcedf6df33214653

I found that Hibernate 3.0 has a method getEntityName on the interceptor interface which lets you provide the actual type name so that you can save proxied objects directly.

Now I found that NHibernate has implemented this in the 2.0.0.Alpha1 release. The method is GetEntityName on the IInterceptor interface. However having implemented this the method never seems to get called. Other methods on the interface get called so the interceptor is configured correctly.

Is this a bug or have I missunderstood something?
