Un bon formatage est votre ami .. –

Utilisez-vous '' au lieu de '' sur votre page pour inclure les bibliothèques js nécessaires pour ajax? –

Quelle version de Primefaces et Mojarra utilisez-vous? – abalogh

Deux réponses postées here (toujours la peine d'essayer!):

1) Inscrivez-vous thecomponent manuellement:

ApplicationFactory af = (ApplicationFactory)FactoryFinder.getFactory(FactoryFinder.APPLICATION_FACTORY); 
javax.faces.application.Application appl=af.getApplication(); 
appl.addBehavior("org.primefaces.component.AjaxBehavior", "org.primefaces.component.behavior.ajax.AjaxBehavior");

2) Une autre chose (lié) à chercher est un espace dans le répertoire de stockage du projet (pour les utilisateurs de Windows au moins)

Espérons que Aidez-moi.

Mathieu.

Vous pouvez également écrire votre propre validateur pour les adresses email. (@FacesValidator ...)
