Comment surmonter le problème de mise en cache de jsf?

Question

J'ai 7 déroulant dans mon jsp (en utilisant JSF tag-Select One Menu), 2 déroulants dépendent des autres 2 déroulants. La portée de mon bean géré est session. J'ai une seule page et mon résultat est un graphique/tableau en fonction de la sélection du menu déroulant. Mais ma sélection est mise en cache et, parfois, lors de l'actualisation du code, mon bean et ma page jsp ne sont pas mis à jour. Ai-je besoin de mettre fin explicitement à la session sur le haricot? S'il vous plaît me suggérer une solution.

page Ma JSP est la suivante:

<% @ taglib uri = "http://www.ibm.com/jsf/html_extended" prefix = "hx" %> < % @ taglib uri = "http://java.sun.com/jsf/core" préfixe = "f"%> <% @ taglib uri = "http://java.sun.com/jsf/html" préfixe = "h" %> <% @ taglib uri = "http://www.ibm.com/jsf/BrowserFramework" prefix = "ODC" %>

Mes faces-config.xml

LoginForm sla.dashboard.form.LoginForm séance

Answer 1

Utilisez @ViewScope au-dessus du nom du bean.

@ViewScope 
public class LoginForm{ 
.. 
} 

(je crois que vous ajoutez le champ d'application dans les faces-config. En JSF2 il n'y a pas besoin de lui.Mieux vaut utiliser une annotation au-dessus de la classe)

BTW, je vous recommande d'appeler votre classe de la manière JSF: LoginBean et pas LoginForm.

Puisqu'il représente un bean géré par JSF.
