[flexcoders] Cairngorm AMFPHP Problem

[creativepragmatic]

Hello,

I am trying to convert an existing Flex/AMFPHP app to Cairngorm but am 
having trouble returning value objects from PHP.

    public function login($userVO)
    {
        $user = new UserVO();

        // yada yada yada, user authenticated, logged and full details 
received

         $user->id = pg_fetch_result($result, 0, "id");
         $user->email = pg_fetch_result($result, 0, "email");
         $user->username = pg_fetch_result($result, 0, "name");
         $user->lastIP = pg_fetch_result($result, 0, "last_ip");
         $user->password = pg_fetch_result($result, 0, "passhash");
         $user->level = pg_fetch_result($result, 0, "level");

         return $user;
    }

Here is the error I get from Flash Player: 

     ArgumentError: Error #1063: Argument count mismatch on ... 
vo::UserVO(). Expected 2, got 0.


Here is what I get from the fault handler:

     Didn't receive an acknowledged message.

     Was expecting mx.messaging.messages.AcknowledgeMessage, but 
received null.


Hopefully, what I am doing will be painfully obvious to someone. 

Thank you in advance for any help,

Orville
