forge.facebook.ui callback never run

I’m trying to use Trigger.io’s facebook methods to display a friend selector. It displays properly but never returns any data.

response is always null even when a friend is selected. According to the Facebook docs it should return request and to fields so I can capture to whom the request was sent.

Here is some sample code:

forge.facebook.ui({
    method: 'apprequests',
    title: 'Create Game',
    message: 'I challenge you to a game!'
}, function(response) {
    console.log('success response');
    console.log(''+response); // As string because logging null errors Catalyst
});

For this, Catalyst outputs

success response
null

And the Trigger Toolkit outputs

[DEBUG] Native call: {
[DEBUG]     callid = "F8446A0D-44AE-46E4-A587-16BEC78EE695";
[DEBUG]     method = "facebook.ui";
[DEBUG]     params =     {
[DEBUG]         message = "I challenge you to a game!";
[DEBUG]         method = apprequests;
[DEBUG]         title = "Create Game";
[DEBUG]     };
[DEBUG]     start = "1354655948.023";
[DEBUG] }
[DEBUG] Returning to javascript: {
[DEBUG]     callid = "F8446A0D-44AE-46E4-A587-16BEC78EE695";
[DEBUG]     content = "<null>";
[DEBUG]     status = success;
[DEBUG] }

Am I doing it wrong? Or is this library not working correctly?

It appears that this is an iOS only issue. It’s happening on the iOS simulator (and device) for both iOS5 and iOS6. But works fine on the Android simulator:

[DEBUG] Native call "facebook.ui" with task.params: {"method":"apprequests","title":"Create Game","message":"I challenge you to a game!"}
[DEBUG] Returning: {"content":{"to[0]":"1175220065","request":"349563028475745"},"status":"success","callid":"548FE13D-69D9-415B-9A94-762D9F7C64B1"}

A fix for this will be included in v1.4.23 Trigger.io platform version.

Your success callback will be invoked with (for apprequests for example):

{"request":"519074534448448","to[0]":"105000524002524"}

Note: your success callback will still be invoked if the user hits cancel: {} will be passed as the callback parameter.

If they hit the x in the top-left corner, your failure callback will be invoked.
