ASP 2.0 and NHibernate 1.2.0 beta

I have a entity class ClassA, which has a one-to-many relationship with ClassB.

When i try to add more than one instances of ClassA's collections of ClassBs i get this error:

Quote:

At least one object must implement IComparable.

So i made ClassB implement IComparable, but the problem still persists, what am i doing wrong?

Code:

public sealed class ClassB  : IComparable<ClassB>
{
     //some stuff


     public int CompareTo(ClassB obj)
     {
            return this.CompareTo(obj);
     }


}
