java - :inputText only gives null back?(未到达 setter )

Question

我正在 jsf 中编写一个寄存器表单:

在 *.xhtml 文件中:

   <h:outputLabel class="Float" for="password" value="Passwort"/>
   <h:inputText id="password" rendered="true" value="#{Register.password}" label="Passwort">
   <f:validateLength minimum="3" maximum="8"/>
  </h:inputText>
 </fieldset>
</h:form>

在 bean 中:

public String getPassword() {
    return password;
}

public void setPassword(String pwd) {
    this.password = pwd;
}

我设置了一个断点，发现我的 setter 没有到达？

为什么？

    private String password = "Fill in!";

    /** Creates a new instance of Customer */
    public Register() {
        //null
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String pwd) {

放置您的 h:commandButton和 <h:inputText与您尝试提交的表单相同...
