GWT Facebook fb:serverfbml problems

Question

Hi,

I have a app that is running on appengine and its written with gwt, the problem is that the fb:serverfbml content takes sometime to load and it doesnt show in any IE. I have the FeatureLoader.js.php import on top and

window.onload = function() { FB_RequireFeatures(["XFBML"], function() { FB.Facebook.init(APPKEY, "/xd_receiver.htm"); FB.XFBML.Host.get_areElementsReady().waitUntilReady(function() { document.getElementById("container").style.visibility = "visible"; document.getElementsByTagName("iframe").style.visibility = "visible"; }); }); };

on the bottom of the .

I've read somewhere that you should use P3P header, but would like to be sure if its necessary.

Thanks.
