AMF connection working on browser, not in stand alone player

Question

Greetings,
I'm trying to communicate my SWF file with PHP using Zend_Amf. I compile the flash side using Flex SDK 4.
Whenever I try to run the swf using the stand alone player (the projector), I always get a NetConnection.Call.BadVersion event. However, when running exactly the same file thorught the player of the browser (even not thoguht a server, just using the file:// kind of address), everything works OK, so I know my code is not completely wrong.
I thought this could be related with the security sandbox. However, I added the folder where my swf file is to the global trusted folder; and actually made sure that Security.sandboxType returns "localTrusted". How ever, that didn't fix anything.
So I'm out of ideas. Any suggestion on where to look next?

Answer 1

Here's my code, in case its needed (it's a pretty straightforward hello world example):
PHP SIDE:
$a = new Amf_Model_Test();
$server = new Zend_Amf_Server();
$server->setClass('Amf_Model_Test');
echo $server->handle();
class Amf_Model_Test
* return string               
public function greet()
    return "hello";
AS SIDE:
public class main extends Sprite
private var _resp: Responder;
private var _nc: NetConnection;
private var tf: TextField;
private var _gateway: String;
public function main()
tf = new TextField();
tf.width = 500;
tf.border = true;
tf.borderColor = 0x0000FF;
addChild(tf);
      _gateway = 'http://cms.loc/amf';
_resp = new Responder(onResult, onFault);
_nc = new NetConnection();
_nc.connect(_gateway);
_nc.client = this;
_nc.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
_nc.call("Amf_Model_Test.greet", _resp);
private function onNetStatus(event: NetStatusEvent): void
trace(event.info['code']);
tf.text = "Status = "+event.info['code'];
private function onFault(result: Object): void
tf.text = "Fault = " + String(result);
private function onResult(result: Object): void
      tf.text = "Result = " + String(result);
In my browser, I get "Result = hello", as expected. In the stand alone player (which is exactly the same version) I get "Status = NetConnection.Call.BadVersion".
