                    value="#{rwUser.usMobilephone}" />

                <h:message for="usMobilephone" style="color:red" />

几种方式.

• 将UIInput组件绑定到视图和第一个的必需属性中,检查第二个的提交值,并在第二个的必需属性中,检查第一个的值(组件是按照它们出现的顺序处理的视图).

  <h:inputText binding="#{usEmail}" ... required="#{empty usMobilePhone.submittedValue}" />    
  <h:inputText binding="#{usMobilePhone}" ... required="#{empty usEmail.value}" />
  

• 检查请求参数映射中是否存在提交的值.

  <h:inputText binding="#{usEmail}" ... required="#{empty param[usMobilePhone.clientId]}" />    
  <h:inputText binding="#{usMobilePhone}" ... required="#{empty param[usEmail.clientId]}" />
  

  或者使用硬编码的客户端ID:

  <h:form id="form">
      <h:inputText id="usEmail" ... required="#{empty param['form:usMobilePhone']}" />    
      <h:inputText id="usMobilePhone" ... required="#{empty param['form:usEmail']}" />
  

• 使用OmniFaces <o:validateOneOrMore>.

  <h:inputText id="usEmail" ... />    
  <h:inputText id="usMobilePhone" ... />
  <o:validateOneOrMore components="usEmail usMobilePhone" showMessageFor="@all" />
