h：未在jsp中验证的组件的消息

Question

我在我的jsp中为多个表单字段指定了h：消息。登录时，将验证会话并将字段替换为注销。登录正确，但未显示字段验证。我还有一个全局h：消息来显示服务器错误。

<c:when test="${userId==null}">
            <div id="fields" class="fieldclass" style="display: none" >

            <div id="sqlserver" class="sqlserver" >
            <h:panelGrid id="grid2"
                columns="2" >

                <h:outputLabel value="Host" styleClass="outputLabel" id="label5"></h:outputLabel>
                <h:inputText id="host" value="#{userBean.host}"  required="true" requiredMessage="Host Name is Mandatory"></h:inputText>


                <h:outputText value="User ID"></h:outputText>
                <h:inputText id="useid" value="#{userBean.userId}" required="true" requiredMessage="User Name is Mandatory"></h:inputText>


                <h:outputText value="Password"></h:outputText>
                <h:inputSecret  id="pwd" value="#{userBean.password}" required="true" requiredMessage="Password is Mandatory"/><h:inputSecret>
   <h:message for="host" style="font-weight: bold; color :red; "></h:message>
   <h:message for="useid" style="font-weight: bold; color :red; "></h:message>
   <h:message for="pwd" style="font-weight: bold; color :red; "></h:message>
</c:when>
    <c:otherwise>
        <center>
        <h:outputText id="logintext">You have successfully logged in!!</h:outputText>

    <br>
<h:commandLink action="#{userBean.logout}" value="Logout" ></h:commandLink>
        </center>
        </c:otherwise>

即使是控制台也没有拿到验证。我做错了什么？
