Creating a Sugar activity

[Gonzalo Delgado]

Hello there, I'm coding an activity for Sugar. It used to run OK, but now I get:

DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name
org.laptop.Activity10485793 was not provided by any .service files

the activity seems to open, but shows no widgets at all. The
documentation from the wiki seems outdated, where could I get
something fresher?

Thanks!
