If I have the following hierarchy:
public abstract class A {...}
public class B extends A {...}
public class C extends A {...}
Should I be able to take an instance from the DB that maps to type B and resave it as type C? I'm using JPA so this would be a merge. I'm thinking I'm going to have to delete the existing instance and then insert the new instance, but I wanted to see if Hibernate could handle that in some fashion.
Thanks,
Derek
