That's right...these are methods inherited from the .NET BindingList class and they know nothing about underlying data. Rather than using these methods, you should instead use the business object's NewEntity() and DeleteEntity() methods which affect both the entity list and the underlying data.

If you have registered a child business object with a parent business object, then the child's entity list is automatically saved when the parent business object is saved.
