java - GWT クライアント側エラー (TypeError): b が null です

Question

私は単純な GWT 2.4.0 RequestFactory アプリケーションを持っています。これは、メソッド呼び出しを起動するとクライアント側の例外で失敗します。

context.checkPassword(tbLogin.getText(), ptbPasswd.getText())
        .fire(new Receiver<EmployeeProxy>() {

            @Override
            public void onSuccess(EmployeeProxy response) {
                Window.alert(response == null ?
                        "Login faild!" :
                        response.getDisplayName()
                                + " login success!");
            }

            @Override
            public void onFailure(ServerFailure error) {
                Window.alert("Somthing wrong");
            }

        });

FireBug および Chrome 開発者ツールには何も表示されません。アラートメッセージを受け取りました：

それは何であり、それを修正する方法は?

「詳細」モードのコンパイル後に同じエラーが発生します。

initialize()RequestFactoryを忘れてしまったに違いありません。
