If you are using a ListVIew (StrataFrame ListView), then you can just set the AutoNavigateToSelectedRecord property to True and set the BusinessObject property to the child BO...then you don't have to worry about the IncludeInForm navigate stuff at all....it is much easier this way.
You will have to be using the 1.6.6 beta to have this new feature. You can get it here: http://forum.strataframe.net/FindPost16061.aspx
