Lorsque j'exécute ma page, je reçois l'erreur suivante :
Code:
javax.servlet.ServletException: Invalid argument looking up property division.matchs of bean frmStoreScores
Or lorsque je n'utilise que des <c:forEach> pour afficher mes information alors je n'ai aucune erreur. J'en conclu que mon form contient bien un objet Division et que cet objet contient bien plusieurs matchs. Mais pourquoi alors les tags nested ne trouve pas d'accès à mes matchs ?
Merci pour vos réponses.
