You must execute the res.view AFTER retrieving the data in the callback. My
first guess in your case:
index : function(req, res){
graph.setAccessToken(req.user.token);
var events = [];
graph.get("/me/events?limit=500", {limit: 500}, function(err, rep)
{
for(key in rep["data"]){
var query = "SELECT eid, name, creator, description, pic,
pic_big, pic_cover, start_time, end_time FROM event WHERE eid=" +
rep["data"][key].id;
graph.fql(query, function(err, event_hash) {
var ev = event_hash["data"][0];
if (ev.creator.toString() == req.user.uid.toString()) {
events.push(ev);
};
res.view({
events: events
});
})
};
});
},
