for the fbconnect login button http://wiki.developers.facebook.com/index.php/Fb:login-button , resizable iframes http://wiki.developers.facebook.com/index.php/Resizable_IFrame, and other fb features to work, the application must include the fb FeatureLoader,

<script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script>

*

grepping for "FeatureLoader", no results were returned in sites/all/modules/fb or in sites/all/libraries/facebook-php-sdk. is the fb module package including FeatureLoader.js.php some other way that hashes the name?

using a zen sub-theme, if i include * in the header, the fbconnect login button doesn't show but the resizeable iframe code works; if * is excluded, the fbconnect login button does show but the resizable iframe code is broken. the resizeable iframe code is implemented in the following way, per the fb wiki page linked above:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="<?php print $language->language; ?>" lang="<?php print $language->language; ?>" dir="<?php print $language->dir; ?>" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
...
  <script type="text/javascript">
      function fixHeight()
    {
      //We need to call FB.CanvasClient.stopTimerToSizeToContent() first because we have called FB.CanvasClient.startTimerToSizeToContent() earlier
      FB.CanvasClient.stopTimerToSizeToContent();
      FB.CanvasClient.setSizeToContent();
    }
  </script>
...
</head>
<body class="<?php print $body_classes; ?>"  <?php if ($_REQUEST['fb_sig_in_iframe'] == 1){print 'onload="fixHeight();"';} ?> >
...
		<!-- http://wiki.developers.facebook.com/index.php/JavaScript_Client_Library -->
        <div id="FB_HiddenIFrameContainer" style="display:none; position:absolute; left:-100px; top:-100px; width:0px; height: 0px;"></div>
		
		<?php 
		if ($_REQUEST['fb_sig_in_iframe'] == 1){
			print '
        <!--start iframe resize script-->
        <!--script type="text/javascript">  
               FB_RequireFeatures(["CanvasUtil"], function(){ 
					FB.XdComm.Server.init("/xd_receiver.htm");
					FB.CanvasClient.startTimerToSizeToContent();
				});
                
        </script-->
		
			';
		}
		?>
</body>

now if you've read this far, you'll notice that the statement

FB.XdComm.Server.init("/xd_receiver.htm");

initializes the xdcomm receiver that you've implemented with fb_connect.module::fb_connect_receiverXX() - and whose output is explicitly included as fb/fb_receiver.html in the package root.

...i can't find where fb_connect_receiverXX() is called anywhere else, grepping for the function in libraries/facebook-php-sdk and modules/fb. the call to

FB.CanvasClient.startTimerToSizeToContent();

must be included just before the closing [/body] tag per the fb wiki page.

will you please shed some light on if/when FeatureLoader and the receiver files are loaded and initialized?

Everything you're writing about is true for the old libraries. If you want those, use the 2.x branch.

http://apps.facebook.com/drupalforfacebook uses the newer 3.x branch. To auto-resize the canvas pages, I have this code near the end of page.tpl.php for the canvas page theme.

  <script type="text/javascript">
  DFF_Canvas = function(){};
  DFF_Canvas.init = function() {
    FB.Canvas.setAutoResize();
  };
  jQuery(document).bind('fb_init', DFF_Canvas.init);
  </script>

I put that right before where $closure is printed.

thanks dave, that worked - with the fb application setting

migrations > new sdks > enabled

however, i now have the bug described at http://drupal.org/node/408432 - i'll post in that thread.

Dave, your script #1 works for 3.x but not 2.x - is there a way to reference this receiver for every fb_cb/* path with 2.0-rc2?
