Dummy RPC works standalone. You can set anything responses at callback.

var rpc:RPCInterface = new RPCDummy();
(rpc as RPCDummy).setDummySuccess("getMail", [
    Mail.create('foo', 'bar')
]);

rpc.getMail(function(mail:Mail):void {
    // success
    // responded mail as dummy
}, function():void {
    // error
});

// rpc.getMail() may callback as error.
(rpc as RPCDummy).setDummyError("getMail", true);
