问题描述
我无法使用facesMessage显示面孔消息
I am unable to show faces messages using facesMessage
Bean代码:
if(condition){
FacesContext fc=FacesContext.getCurrentInstance();
fc.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_FATAL,"Rounding Rule Saved","R Saved"));
}
查看代码:
<p:messages autoUpdate="true" showDetail="true" globalOnly="true" id="msgId"/>
但是我没有收到消息，我在做什么错了?
But I am not getting messages, what am I doing wrong?
我的项目流程是:
- 用户单击查看页面上的编辑按钮
- 重定向到编辑页面
- 提交返回查看页面后
- 呈现消息(我没有收到)
查看代码(rouning_rule_master.xhtml):

推荐答案
我不确定是否是您的情况.但是，如果您在生成消息后进行重定向，则它们将在重定向过程中丢失.您需要确保在页面流中，faces配置中没有重定向-或任何其他方式.
I am not sure if it is your case. But if you redirect after generating the Messages, they are lost in the redirect process. You need to make sure there is no redirect in the faces config - or any other mean - in your page flow.
