Probléme avec le scope request
Salut,
J'utilise un scope request pour le managed bean. Je voudrais savoir si c'est possible d'éviter de crée à chaque fois un nouveau bean lors de chaque rafraichissement de vue.
En effet, avec ma a configuration actuelle, lors de chaque rafraichissement de ma vue, on utilisant par exemple un F5, il y a création d'un nouveau managed bean. Or mon constructeur fait beaucoup choses et crée beaucoup de structures. Ce qui me cause une perte énorme en temps d'exécution.
Voila ma configuration
