            this.server.sendMessage(this, fxv);
            return;
        }

    }
}

and when I’m doing a compilation i got error:

1020: Method marked override must override another method.

in block:

override public function onRegister() : void
        {
            this.gameStateProxy = facade.retrieveProxy(GameStateProxy.NAME) as GameStateProxy;
            return;
        }

Please help me solve this problem
Thanks
