Hi,

I'm writing an app in Flex and I'm trying to register a function in the AS code so it can be called from the enveloping JS.

The AS3 code looks like this:

                ExternalInterface.addCallback("functionname", functionname);

If the .swf were called "myspaceApp," for example, then I should be able to call myspaceApp.functioname() from the javascript, but I get the following error on attempts to load the app:

 SecurityError: Error #2060: Security sandbox violation: ExternalInterface caller test.swf cannot access http://api.msappspace.com/apprendering/renderapp.ashx?opensocial_token=mAa9IwDossX0rZYtutVeHtOwVDghgmxeKjPWgINq1N%2bArnbl8YutjP27q6vhA9WtcvGPj9yny4j84%2b05wZrPOb%2bFkJCT9jNV50aEcZ5uArA%3d&opensocial_surface=profile.

Any ideas? 

 When you embed your swf, set 'allowScriptAccess=always'. This lets your swf call javascript on the page.

Also, inside your swf, you might want to call flash.system.Security.allowDomain('*'). This will allow javascript to call actionscript in the swf

Hey thanks for the reply, that fixed it.  I was experiencing cross-browser problems as well, but the following lines fixed that as well, for anybody who's interested:

function getFlashMovie(movieName) {
  var isIE = navigator.appName.indexOf("Microsoft") != -1;
  return (isIE) ? window[movieName] : document[movieName];
 }
 
function fn(){
   getFlashMovie("swfname").fnName();

}

work in IE?
