FB + Adobe AIR: Posting Bug

My friends were asking me to help them to debug an interest problem that they are facing with the Facebook Graph Desktop API.

The scenario as follows. A user log in to the desktop application (Adobe AIR) through Facebook and he decided to post something on his Facebook wall through the application and decides to log out of the Facebook and Application. If a second user tries to log in and post something to his Facebook wall using the application, the message will appear on the wall on the first user, rather than the second user. Therefore here's a fix to that issue if you are using the source files of the 'Facebook Graph Desktop API'.
You have to modify the following function of the following file - com\facebook\graph\FacebookDesktop.as From

    public static function api(method:String,
                     callback:Function,
                     params:* = null,
                     requestMethod:String = 'GET'
    ):void {
      getInstance().api(method,
        callback,
        params,
        requestMethod
      );
    }

To

    public static function api(method:String,
                     callback:Function,
                     params:* = null,
                     requestMethod:String = 'GET'
    ):void {

      if(params != null)
      {
        if (getInstance().session != null) {
          params.access_token = getInstance().session.accessToken;
        }
      }
      getInstance().api(method,
        callback,
        params,
        requestMethod
      );
    }
