fb:serverfbml not rendering in ie7

I'm writing a Facebook iframe/Facebook Connect application and one of the pages includes a multi-friend-selector. It renders perfectly in every browser I tried (FF/Mac, Safari/Mac, IE8/Win) but does not render at all in IE7/Win. I waited and waited (in case it was just being slow) and it never appeared.

Here's my code.

<fb:serverfbml style="width:750px;height:700px">
<script type="text/fbml">
<fb:fbml>
<fb:request-form
 action="<? echo $invite_href; ?>"
 method="post"
 type="<? echo $app_name; ?>"
 content="<? echo htmlentities($content,ENT_COMPAT,'UTF-8'); ?>">
 <div class="clearfix" style="padding-right:20px;" height="500" width="750">
 <fb:multi-friend-selector
  actiontext="Here are your friends who don't have <? echo $app_name; ?> yet. Invite your friends and let them help too - it's free!"
  exclude_ids="<? echo $friends; ?>" />
 </div>
</fb:request-form>
</fb:fbml>
</script>
</fb:serverfbml>

The other required things (FeatureLoader.js and all that) are (must be) properly included, since the friend selector and every other fb tag I use around the application works perfectly. The serverfbml tag is the ONLY thing giving me trouble in IE7. Most people seem to have a problem with the selector rendering at an annoying 150px tall - I can't seem to find anyone else who has a problem with it not 开发者_StackOverflow中文版rendering at all.

You do not need the closing tags because you're rendering FBML insdie the serverfbml tag, not xfbml. Another thing I noticed is you're passing PHP variables into it, whereas I'm pretty sure Facebook strips out all your php from within the server fbml, I may be wrong though.

Another SO post, which solved my problem: Why does this XFBML markup embedded within an iframe'd facebook application not display anything?

Are you using IE Tester to test ie6? If so it fails to render, this is an IE Tester bug.

Facebook is encouraging developers to switch to Requests 2.0. FBML is being deprecated and so reliance on fb:serverFbml will likely by phased out at some point this year. Fortunately there is a MUCH easier way to do this using the JavaScript SDK and it even works on websites.

FB.ui({method:'apprequests',...});
