Hello all, I have the following situation. A person can be both student and vendor. Let's say that I save the person first, and after that the person becomes a vendor. Using inheritance in NHibernate (mapped as table per class) i cannot save the person first, and make that person entity also a vendor. I understand the NHibernate team which says that you cannot change the type of an object (.NET object for example) once the object has been created. But, what if I ask the NHibernate session "get me the object vendor with the id of the object person" and then, the session, even though sees that the vendor does not exist, sees also that the person (which is the superclass of vendor) exists, and gives me a vendor object with the properties from person filled in and after that the vendor object can be persisted into the database? This post is addressed mainly to the NHibernate team, so any follow up from them will be appreciated. Thanks.
