J'ai pas compris de quoi il s'agit pourtant que la page semble juste lorsque j'elimine la partie ou je veux récuperer le tableau l'erreur disparait mais lorsque je l'ajoute ça s'affiche!
Merci pour votre aide svp !

normalement cette méthode doit se trouver dans le managedBean et aussi je en vois pas où est votre entity manager ? On a besoin de voir aussi le sessionBean dans lequel vous fêtes la requête de recherche.
