Using FBML in a ruby sinatra app

Question

Hi,

I'm building an application in ruby using the sinatra framework and am having trouble with rendering some fbml elements.

I'm currently trying to render an fb:multi-friend-selector so the user can select which friends they want to invite. However, when I write the following in my code:

<fb:fbml> 
    <fb:request-form action="/inviteFriends" method="POST" invite="true" type="MY APP" content="Invite Friends" > 
         <fb:multi-friend-selector showborder="false" actiontext="Invite your friends to use YOUR APP NAME."> 
    </fb:request-form> 
</fb:fbml>

Nothing renders with the text above. I've included the regular facebook xsds for the taglibs in my html tag and have tested fbml on the page using the following code:

<fb:name useyou="false" uid="USER_ID" linked="false"/>

This code works correctly and displays the user's name.

I've tried a simple example like that on http://wiki.developers.facebook.com/index.php/Fb:random but again nothing is rendered in the browser.

Do I need to include some special javascript or anything?

I would greatly appreciate some help with this.

Thanks in advance -gearoid.

I've just realised that you have to use the server:fbml tags for this to work.

Facebook documentation could really use some work :)
