Seam International/Faces Messages is not working

Hendy Irawan Newbie

I fire the exception by handling a @Before @RenderResponse JSF phase event :

 

public class FacesSecurity {

 

private transient Logger log = LoggerFactory.getLogger(FacesSecurity.class);

@Inject Identity identity;

@Inject Event<NotLoggedInException> notLoggedIn;

 

public void checkPermissions(@Observes @Before @RenderResponse PhaseEvent event) {

FacesContext faces = event.getFacesContext();

HttpServletRequest request = (HttpServletRequest) faces.getExternalContext().getRequest();

String viewId = faces.getViewRoot().getViewId();

log.debug("Checking permissions for {}:{} on {}", new Object[] {

request.getRemoteAddr(), request.getRemotePort(), viewId });

if ("/pages/article/post.xhtml".equalsIgnoreCase(viewId)) {

if (!identity.isLoggedIn()) {

log.debug("{}:{} is not logged in on {}", new Object[] {

request.getRemoteAddr(), request.getRemotePort(), viewId });

notLoggedIn.fire(new NotLoggedInException());

}

}

}

}

 

Then using @Observes to catch the exception, setting the message, then redirect:

 

public void handleNotLoggedIn(@Observes NotLoggedInException evt) {

ExternalContext external = faces.getExternalContext();

HttpServletRequest request = (HttpServletRequest) external.getRequest();

String viewId = faces.getViewRoot().getViewId();

log.debug("Redirecting {}:{} request {} to login page", new Object[] {

request.getRemoteAddr(), request.getRemotePort(), viewId });

faces.addMessage(null, new FacesMessage("Silakan login untuk melanjutkan."));

try {

external.redirect(external.encodeRedirectURL("login", null));

} catch (IOException e) {

throw new RuntimeException("Error during handling NotLoggedInException", e);

}

}

 

which works wonderfully. However, I tried changing it with @Inject Messages without success:

 

@Inject org.jboss.seam.international.status.Messages messages;
...
messages.warn("Silakan login untuk melanjutkan.");

 

Using @Inject Messages, no FacesMessage is shown at all.

 

Any suggestions ?
