Hi, I'm going to be using NHibernate on a project I'm working on and I'm in the midst of reading the documentation.

In http://www.hibernate.org/hib_docs/nhibe ... tions.html

"When you make the instance persistent - by calling Save(), for example - NHibernate will actually replace the HashedSet with an instance of NHibernate's own implementation of ISet"

This scares me. Does this really mean that if I save an entity graph, I can no longer use the custom functionality I have added to my own implementain of ISet that I use in my graph collections? This seems so insane that I though I should double check with the community....

Thanks!

Mike
