Facebook.init returns null callbacks

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use the 1.81 swc
2. Call Facebook.init(APP_ID,handleCallback)
3. See null in both success and fail objects

What is the expected output? What do you see instead?
We are supposed to see a response and/or fail object but in this case we see a 
null in both items. Do we need to set something on the facebook app set up to 
make sure we get some values here?

Thanks in advance

I am seeing the same issue and just started seeing it in my app (that has been 
in production for months) today.

actually, I was using 1.6.1. I upgraded the swc to 1.8.1 and it works now!

I am guessing this:

Breaking Change: JavaScript SDK to oauth:true on December 13th
By Jerry Cain - Monday at 17:00
As part of our continued efforts to migrate all apps to OAuth 2.0, we are 
opting in all apps using the new JavaScript SDK to OAuth 2.0 tomorrow at 11am 
Pacific Time. The deadline to support OAuth 2.0 was October 1st, 2011.

The new JS SDK with OAuth 2.0 was introduced in July. Tomorrow, on December 
13th at 11am, we will automatically default the oauth param to true in FB.init. 
With this change, please ensure that you are using FB.getAuthResponse to obtain 
the access token. Read more about the specific changes that you need to make 
here.

I was using 1.6.1 and upgraded to 1.8.1 and don't see a change.
Is there a page where we can find the changes we need to make to support this, 
specifically for action script?

EVERYBODY!!!! LISTEN TO ME!!!!!
check your permisiions for the facebook request.
I removed"read_stream" and it came back to life.

//original permission
//var opts:Object = {perms:"publish_stream, user_photos, user_status, 
friends_status,friends_photos, read_stream"};
//new permission
var opts:Object = {scope:"publish_stream, user_photos, user_status, 
friends_status,friends_photos"};
Facebook.login(onLogin, opts);

I have upgraded FB as3 api to 1.8.1. and one application worked perfect. But 
other two don´t working.
Could be some configuration from the options on application as "Encrypted 
Access Token" or "Enhanced Auth Dialog"?

Please help I have my customers desperate :S
Thank you!

Actually, wth regards to comment #8 where you said you 'removed "read_stream"':

I think that, far more crucially, you changed the 'perms' parameter to 'scope', 
which is part of the update for useing the 1.8.1 API and OAuth 2.0.

Similarly, if you're posting to a user's Wall or photo albums and have this 
kind of object declaration:

var photoParams:Object = {
    image:myBitmap, 
    message:"My uploaded photo",
    fileName:"uploadedPhoto",
    access_token:Facebook.getSession().accessToken
};

...the getSession() method is no longer available in 1.8.1, so you'll have to 
update your access_token value to:

    access_token:Facebook.getAuthResponse().accessToken

Hello guys, as per what everyone has been saying, please change your api to 
1.81 which is the latest as OAuth2.0 is forced on everyone now. 
With regards to getting back null values, its said already be dafault that 
there wont be any errors, so that means if u get a double null, you have an 
issue with your calls. 
Now to move forward, what you can test is first is your call being made, in my 
instance it was and it was just not getting back any data. 
If you are having getting the Facebook.init to fire in teh first place set all 
your settings in advanced to disabled except the remove deprecated calls (first 
one)
This should help everyone out. 
Remember check your api key, check your order of calls and make sure your call 
is in a place which can be fired.

Any problems email me mtopiwalla@gmail.com im more than happy to help.

Hello

Same problem here.
I updated my app to the latest library(1.8.1) and the init doesn't work.

I created a new app in Facebook Apps and a new app in my Flash Bulder with 
minimal configuration...

Here is my code:

            public const fbAppId:String = "xxxxxxxxxxxx";

            protected function onInit(event:FlexEvent):void
            {
                Facebook.init(fbAppId, handleInit);
            }

            private function handleInit(result:Object, fail:Object):void
            {
                trace("App Init");
            }

The handleInit function never calls.

Hello,

I solved the problem... for me :)

<script type="text/javascript" 
src="http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>
<script type="text/javascript" 
src="http://connect.facebook.net/en_US/all.js"></script>    

I added these 2 lines in the head tag of my html where my swf is embeded, and 
this

<div id="fb-root"></div>

to begin of body tag. This div already had it in my html but not those two 
lines.

For me is working great :)

After a long struggle I managed to get the callback fired, but the received

Hey everyone,

Don't know if you guys are still having issues, but I was struggling with this 
December 13 Facebook OAuth update for the longest time and finally just got it 
working.

A few things of importance that ended up working for me:

1) Check out this link: 
http://saket.the-confluence.com/2011/12/18/facebook-issue-395/
Helped me a lot!
-In particular, make sure you download the latest API and get rid of the old 
one. 

2) Be sure that you're using scope instead of perms in the Facebook.login
protected function login():void{
     Facebook.login(loginHandler, {scope:"email"});
}

3) I had a FBJSBridge.js file, so in it:
-Make sure to change "response.session" to "response.authResponse". 
-If you have "response.perms" change that to "response.scope". 
-Also change the fb_getSession() function to 

function fb_getAuthResponse() {
    authResponse = FB.getAuthResponse();
    return FB.JSON.stringify(authResponse);
}

-In my fb_init, I also changed "auth.sessionChange" to 
"auth.authResponseChange" as seen below:
function fb_init(opts) {
    FB.init(FB.JSON.parse(opts));

    FB.Event.subscribe('auth.authResponseChange', function(response) {
        updateSwfSession(response.authResponse);
    });
}

4) In the index.htm:

-Make sure the support libraries appear in this order:
<script type="text/javascript" 
src="http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>
<script type="text/javascript" 
src="http://connect.facebook.net/en_US/all.js"></script>

-Facebook init returns null apparently because of how you embed the flash 
player. So make sure it's like this:
swfobject.embedSWF("swfFileName.swf", "flashContent", "760", "800", "10.0", 
null, null, null, {name: "flashContent"})

-I also had a redirect uri, and I had to change the uri from 
'https://graph.facebook.com/oauth/authorize?client_id='+id+'&scope='+perms+'&red
irect_uri='+uri+params; to what you see below:

function redirect(id,scope,uri) {
     var params = window.location.toString().slice(window.location.toString().indexOf('?'));
     top.location = 'https://www.facebook.com/dialog/oauth?client_id='+id+'&redirect_uri='+uri+params+'&scope='+scope;                          }

Hope this helps a bit!

Hello everybody!

I also have double null issue.
Looking at Facebook.as you can see lines 857-889(handleAuthResponseChange 
function). As I understand from that code - there is NO WAY to get (fail != 
null).

Also, as I see, there is no way to get (authResponse != null) before user press 
"Allow" button at facebook permissions dialog.

So we have two situations: Facebook.init or login will return
1. (null, null), if user doesn't allowed the permissions in dialog
2. (authResponse, null) in other way.

If I am right, may be as3 api team will at least add "fail always null" to docs?

[GoogleCodeExporter]

I had the double null issue too, but just updating the Facebook Graph Api did 
it for me. 

I was getting and storing the accestoken trough the session, but session isn't 
available anymore. You can still get the accestoken via 
"Facebook.getAuthResponse().accessToken".

To make it work you must make sure to pass a name as an attribute when 
embedding the swf
var flashvars = {};
var params = {allowScriptAccess: "always",wmode: "window"};
var attributes = {id:"flashContent",
        name:"flashContent" // Must be included for js to communicate with flash
        };
swfobject.embedSWF("myswf.swf","flashContent", "730", "525", "11.0.0", 
           "expressInstall.swf",flashvars, params, attributes);
