PanelTabbed et nullPointerException
Bonjour,
J'essaie désespérément de faire fonctionner un PanelTabbed basique mais j'obtiens à chaque fois la même erreur. J'ai repris l'exemple donné sur MyFaces Trinidad. Peut-être dois je modifier quelque chose dans mon web.xml? Voici mes sources et le message d'erreur donné par Tomcat :
