Bonjour,
J'ai un petit souci pour injecter un managed bean en @ApplicationScoped dans une ressource web socket de primefaces :

Tout se passe correctement jusqu'à l’exécution de la méthode "ucm.test();", (si j’enlève l'appel de cette méthode il n'y a plus de problème, j'ai l'impression qu'il n'arrive pas à injecter mon Managed Bean ) voici l'erreur :
