Sebastian,
First of all, Paul is correct that MM VFP COM objects automatically run in private data sessions. Secondly, the business objects are simply getting information from goApp rather than storing a reference to themselves. Once goApp is created, business objects can use goApp to reference manager objects such as the Factory and the Database Manager.
