Maybe they mean may, as in, never.

I believe that the BMessage constructor and the Instantiate function are
for two separate things. It seems strange to me that they would have two
different functions for doing the same thing. I believe the Instantiate
function is for creating BTranslatorRosters that were archived with the
Archive member function, and the BMessage constructor works as you've used
it.  I would try using the Archive member function with a working
BTranslatorRoster, then try to create a new BTranslatorRoster using
Instantiate with the BMessage that the Archive member function created.

|?
|I cannot even create a BView since I am not a BApplication...

|stuff)?

I would imagine that you would have to create a GUI app, passing the BView
that you get from MakeConfigurationView to a BWindow. You could probably
start with the HelloWord example and modify it a bit.
