You're right. However, after I've added a panel with id for the message, it's still not displayed. <a4j:outputPanel id="loginPanel"> | <h:panelGrid rendered="#{! empty facesContext.maximumSeverity}"> | <h:messages for="loginPanel" styleClass="message" /> | </h:panelGrid> Is there anything that I could have erred that caused this message to be dropped after the Authenticator.authenticate() method called?
