Question

我在JBoss EAP 6.0上有一个JSF 2.1 + RichFaces 4.0 webapp。我无法使用FacesMessage显示从bean到用户的自定义错误消息。我正在使用addMessage()添加消息。但是，该消息未显示在<rich:messages>和我的控制台中：

INFO [javax.enterprise.resource.webcontainer.jsf.renderkit]（http-localhost / 127.0.0.1：8888-3）警告：FacesMessage已入队，但可能尚未显示。 sourceId = null [severity =（ERROR 2），summary =（mobile =应大于10 degits），detail =（）]。

由于ui：composition中没有模板属性，我假设页面是顶级的。然后缺少 h：body ，这是一个例子：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:a4j="http://richfaces.org/a4j"
    xmlns:rich="http://richfaces.org/rich">
    <h:head/>
    <h:body>
        <h:form .....
    </h:body>
</html>

全局消息未显示在<rich：messages> </rich：messages>中
