Are you saying that your verification is failing in the case when
there aren't any friends with the application installed? If so, try
this verification code instead.
if (!data || data.hadError() || data.get('viewer_friends').hadError())
{
// Error retrieving data
return false;
}
var viewer_friends = data.get('viewer_friends').getData();
if (viewer_friends.size() < 1) {
// No friends with the app
return false;
}
Notice that I'm using the opensocial.Collection size() method to
return the number of objects in the collection. Just move this snippet
to the top of your response function and you should be good to go. Let
me know if I didn't answer your question or if this still doesn't
work, and provide more details about what the problem is. Thanks.
