Filtre timeout erreur de faceContext
J'ai suivit le blog de Djo.mos [Java] Gestion des sessions expirées dans JSF (rebelote) pour faire un filtre et gérer les session timeout. Je l'ai adapté à ma situation. qui est de redirigé sur ma page d'index.jsf. Mais j'obtiens une erreur facecontxt == null. Si quelqu'un à une idée (ou plusieurs ^^)
