我在 JBoss EAP 6.0 上有一个 JSF 2.1 + RichFaces 4.0 webapp。我无法使用FacesMessage. 我正在使用添加一条消息addMessage()。但是，该消息没有显示<rich:messages>在我的控制台中和我得到的控制台中：
INFO [javax.enterprise.resource.webcontainer.jsf.renderkit] (http-localhost/127.0.0.1:8888-3) 警告：FacesMessage(s) 已入队，但可能尚未显示。sourceId=null[severity=(ERROR 2), summary=(mobile no 应该大于 10 位), detail=()]。
