I think I see where the miscommunication is here. I was making the assumption that the state of the biz object be reestablished prior to the use of the properties. Otherwise, what you are saying is entirely correct.

>It's the same thing. You can't rely on a value of a property to be there if called from the client. You need to return the value from a method. If you need multiple values you can use a parameter object.

A Parameter object - yes, this is what I'm looking for. Can you be more explicit.
