John,
i don't quite get what this extra function is for, either.
why not set self.appIsOnline = success directly instead of
self.passLoadResult( success ) ?
or why not set self.online = success and save the setter, or do you
intend to use the setter appIsOnline at some point?
if you don't plan on using it from outside the class, the setter should
not be there (appIsOnline as read only property).
