Hola Pablo!
¿Puede probar este código?
function loadFriends()
{
// create a request
var req = opensocial.newDataRequest();
var viewerFriends = opensocial.newIdSpec({ "userId" : "VIEWER",
"groupId" : "FRIENDS" });
var opt_params = {};
opt_params[opensocial.DataRequest.PeopleRequestFields.MAX] = 100;
req.add(req.newFetchPeopleRequest(viewerFriends, opt_params), 'info');
req.send(onLoadFriends);
}
function onLoadFriends(ret)
{
var data = ret.get('info');
var html = new Array();
html.push('<ul>');
if (!data.hadError())
{
var viewerFriends = data.getData();
viewerFriends.each(function(person){
html.push('<li>' + person.getId() + '---' +
person.getDisplayName() + '</li>');
});
}
html.push('</ul>');
}
Saludos,
Robson Dantas
