Hi,
I have serious problem with iframe application. I need to use many external JS libraries and other dynamic stuuf so FMBL application can't be done. When I call require_login() I get applicaition installing dialog when app is not already installed, which is ok. But then after authorization application enters an endless redirect loop with parameters like auth_token, installed and so. Yesterday I managed to fix this, but today it's broken again... What the heck is happening with FB? It's driving me crazy to find a sollution, none of ones found on net doesn't seem to be working.
So far I tried:

None of the above worked... According to those and some FB docs: http://wiki.developers.facebook.com/index.php/FB_RequireFeatures http://wiki.developers.facebook.com/index.php/Cross_Domain_Communication_Channel
My example test files look as follow:
<?php
//Link in library.
require_once '../application/vendor/Facebook/facebook.php';
//Authentication Keys
$appapikey = 'XXXX';
$appsecret = 'XXXX';
//Construct the class
$facebook = new Facebook($appapikey, $appsecret);
//Require login
$user_id = $facebook->require_login();
?>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<title></title>
</head>
<body>
<script src="http://static.ak.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script>
This is you: <fb:name uid="<?php echo $user_id?>"></fb:name>
<?php var_dump($facebook->$this->facebook->api_client->friends_get())?>
<script type="text/javascript">
FB_RequireFeatures(["XFBML"], function(){
FB.Facebook.init("<?=$appapikey?>", "xd_receiver.html");
});
</script>
</body>
</html>
And cross-domain file xd_receiver.html is:
<!doctype html public "-//w3c//dtd xhtml 1.0 strict//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>cross-domain receiver page</title>
</head>
<body>
<script src="http://static.ak.facebook.com/js/api_lib/v0.4/XdCommReceiver.js" type="text/javascript"></script>
</body>
</html>
How do I get it working?
I'm using Kohana framework to do this and already replaced header('Location') with url::redirect() in facebook php library.
