[jboss-user] [JBoss Seam] - FacesMessage enqueued, but not displayed.

Hello, I have a simple login page and an Authenticator all based on code generated with Seam-gen. They used to work. And now I don't know which code I modified that resulted me with this problem. When the Authenticator caught an AuthenticationException, it would write to FacesMessage like the following: try { | long sessionId = clientMgr.login(identity.getUsername(), identity.getPassword()); | ... | } catch (AuthenticationException e) { | switch (e.getRejectReason()) { | case USER_CREDENTIAL_NOT_FOUND: { | facesMessages.add("#{messages['login.failed.UserCredentialNotFound']}"); | break; | } | case USER_CREDENTIAL_UNMATCHED: { | FacesMessages.instance().add("#{messages['login.failed.UserCredentialNotMatch']}"); | break; | } | And on my login page, I have the following: <div class="body"> | <h:form id="login"> | <rich:spacer height="10" /> | <a4j:outputPanel id="loginPanel"> | <rich:panel> | <f:facet name="header">#{messages['login.logon.legend']}</f:facet> | <div class="dialog" align="center"> | <h:panelGrid> | <h:messages styleClass="message" /> | </h:panelGrid> | Yet when I tried to login with invalid username/password, I got no error message displayed on the page and the following warning in the log: anonymous wrote : 09:46:56,968 INFO [lifecycle] WARNING: FacesMessage(s) have been enqueued, but may not have been displayed. | How does Seam decide when to display or not to display an enqueued FaceMessage? Thanks for your help. -tony View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4082242#...
