void onActivate(String message)  
    \{  
        System.out.println("another page is activated!");  
        this.passedMsg = message;  
    \}  
    /\*  
     \* report to the tapestry when activation context is asked in terms of  
     \* to methods, the onPassivate method will return the parameter that need to  
     \* be remembered  
     \*/  
    String onPassivate()  
    \{  
        System.out.println("anotehr page is passivated..");  
        return passedMsg;  
    \}  
    @OnEvent(value="submit", component="userInputForm")  
    void onFormSubmit()  
    \{  
    System.out.println("Handling form submission!");  
    \}  
    @OnEvent(value="submit",component="loginForm")  
    void onLoginFromLoginForm()  
    \{  
        //no output  
        System.out.println("adf--------------");  
    \}  
    void onSubmitFromUserInputForm()  
    \{  
        System.out.println("a----------------df--------------");  
    \}  
    void onSubmit()  
    \{  
        System.out.println("-----------a----------------df--------------");  
    \}  
\}

使用了两个方法，

1.  Object onSuccessFromStartForm()  
    \{  
        System.out.println(username + " 14 " + zhize);  
        if(zhize ==  null || username == null )  
        \{             
            return Start.class;  
        \}  
        return Main.class;  
    \}

和

2.   Object onSelectedFromSubmit(String name, String zhize)  
    \{  
        System.out.println(name + " 12 " + zhize);  
        if(zhize ==  null || name == null )  
        \{             
            return Start.class;  
        \}  
        return Main.class;  
    \}

来和startForm 的  <t:submit t:id="submit" value="请进入系统"/> 按钮链接，

要注意的是2不能返回值，而一不能带参数，所以2应该是

Object onSelectedFromSubmit(String name, String zhize)  
    \{  
        System.out.println(name + " 12 " + zhize);  
        if(zhize ==  null || name == null )  
        \{             
        \}  
    \}

必须以submit开始
