我是jsf和richfaces的新手我想创建两个不同形式的单曲面板我能做到吗？该页面一直有效，直到我添加了一个在弹出窗口中使用动作监听器的新按钮

我收到以下错误

INFO: WEB0671: Loading application [My_community] at [/My_community]
INFO: My_community was successfully deployed in 19,911 milliseconds.
SEVERE: /index.xhtml @21,61 id="loginformvalidate" Unhandled by MetaTagHandler for type org.richfaces.component.behavior.ClientValidatorImpl

页面运行但弹出窗口上的提交按钮生成的动作侦听器无效如果我做错了，请告诉我

Answer 1

你确定，富有：验证者可以生孩子吗？我认为它应该在你要验证的字段内：

<h:inputText label="username" id="username" value="#{loginMB.username}" required="true" requiredMessage="user name is requried">
    <f:validateLength minimum="5" />
    <rich:validator/>
</h:inputText>

jsf页面动作listioner无法正常工作
