在GuiController中直接创建阶段，在下一行执行它，我可以正确地看到包含所有元素的窗口

。。。我真的不知道该怎么想，调试了一整天，什么都没得到，你能帮我吗

我关闭了框架，因为我的想法是为每个“阶段”打开一个窗口，服务器通过套接字发送正确的阶段。 如前所述，这是来自服务器的guihandlenotifies的内容：

    public GuiHandleNotifiesFromServer(Socket socketServer, ControllerClient controllerClient) {

        super(socketServer, controllerClient);

    }

        switch(phase) {

        case "InsertGameTypePhase":

            System.out.println(session.getControllerClient() + " " + phase + " DEBUG buildPhaseObjectDependingOnServerPhase");

            this.phase = new ChoiceGameTypePhase(session.getControllerClient());
