问题
I am unable to show faces messages using facesMessage
Bean code :
if(condition){
FacesContext fc=FacesContext.getCurrentInstance();
fc.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_FATAL,"Rounding Rule Saved","R Saved"));
}
View code :
<p:messages autoUpdate="true" showDetail="true" globalOnly="true" id="msgId"/>
But I am not getting messages, what am I doing wrong?
EDIT:
My project flow is :
- User click on edit button on view page
- Redirect to edit page
- After submitting return to view page
- Render message(which I am not getting)
View code (rouning_rule_master.xhtml) :

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.
