Publish to Facebook Stream in as3

Question

Hi, I am trying to publish to a users stream when they click a share button in my flash app that i have living in a tab on a fan fan. I basically have my swf embedded on a page that has a java script function that calls the facebook share dialogue. Here is what i got so far: // flash embedd

<fb:fbjs-bridge/> 

// share function

<script>

function publishfeed() { var attachment = {'media':[{'type':'image','src':'http://bit.ly/AJTnf','href':'http://bit.ly/hifZk'}]};

Facebook.streamPublish('', attachment); }

In my flash file, I try using this code to get it to pull the javascript funtion, but no luck.

function jspopupWindow(event:MouseEvent):void {

var request:URLRequest = new URLRequest("javascript:publishfeed()"); navigateToURL(request,"_blank"); } share_btn.addEventListener(MouseEvent.CLICK, jspopupWindow);

Can anyone help me, what am i missing? thanks a
