Make sure you set the props before opening the window - Sugar  
unfortunately does not track property changes. Neither does it track  
service creation, but that's a different issue.

Also, you might find sugar-native-factory useful, which handles the  
factory-side of dbus for your native activity:

The current (pre-rainbow) activity requirements are documented here:

Hopefully someone will update this with rainbow-specifics.
