Accessing Joomla User Id Inside Flex 4.5

Question

Alright, I posted this over at the Joomla forums as well and figured I'd try here as well... Here's my delima:
I have a flex 4.5 app that I am trying to utilize on a joomla page and I need it to access the currently logged in user id. So, here is what I have so far: My PHP class: 
Code:
<?php class userId {
      public function getuserID($userID) {
         //Defining Joomla path, variable, and determining user id
         define( '_JEXEC', 1 );
         define('JPATH_BASE', dirname(__FILE__) );
         define( 'DS', DIRECTORY_SEPARATOR );
         require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
         require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
         $mainframe =& JFactory::getApplication('site');
         $mainframe->initialise();
         $mainframe->route();
         $userID = & JFactory::getUser();;
         return $userID;
   } } ?>
 My protected function in Flash Builder CS5: 
Code:
protected function username_creationCompleteHandler(event:FlexEvent):void                   {                         getuserIDResult.token = userId.getuserID($userId);                   }
 And for testing purposes, I just want to display it in a text label: 
Code:
<s:Label id="username" width="60"
creationComplete="username_creationCompleteHandler(event)"
text="{getuserIDResult.lastResult}"/>
 Now, I have the release build in an article in Joomla. But when the page loads, I get the following error in the Flex app: 
Quote:
Channel disconnected
Channel disconnected before an acknowledgement was received
 Now, I am pretty sure I have double checked my source code in flex through and through. So I don't think the problem is there (I may be wrong though...). And if I comment all the code out inside the PHP function and declare the userid variable to any static string it returns that string perfectly in the flex app. So my feeling is it is in the PHP class... Anyone here see where I am going wrong?

Answer 1

well I've tried with something much simpler and it still doesn't work. So I removed all scripts and all components and just added an mx:Button.
The button is initialised but it's creationComplete event does not get fired.
So I'm not exactly sure what's wrong.
I have a mx:Module (DashboardModule) which is loaded using Cairngorm's ModuleViewLoader and that includes the following:
        <presentation:DashboardView
            width="100%" height="100%"
            verticalScrollPolicy="on" horizontalScrollPolicy="on"
            userProfile="{shell.userProfile}"/>
DashboardView is the code I've shown you above.
But as I said, even If I remove all scripts and components from DashboardView.mxml and just leave an mx:Button with a creationComplete handler and an initialize handler, the creationComplete handlernever gets invoked.
Could this be something with mx:Module and Cairngorm's ModuleViewLoader?
I should say that the Module's creationComplete handler gets invoked and so does the DashboardView's creationComplete handler gets invoked but not DashboardView's children.
