I will tell what i am doing :
1.
req.add(req.newFetchPersonRequest(opensocial.DataRequest.PersonId.VIEWER),
"viewer");
2.
req.add(req.newFetchPeopleRequest(opensocial.DataRequest.Group.VIEWER_FRIENDS),
"viewer_friends");
3. req.add(req.newFetchPersonAppDataRequest('VIEWER', 'comps'),
'data');
4. req.add(req.newFetchPersonAppDataRequest('VIEWER_FRIENDS',
'comps'), 'viewerFriendData');
5. req.send(onLoad);
In line 4, I am getting my application data ('comps') for all the
friends of the viewer. If my application is not installed in even one
of my friends' profile, the total thing goes wrong and even the
viewer's information is not sent back. I am getting: ==TypeError:
data.get("viewer") has no properties==
