selectOneMenu et action sur champ input
Je voudrais créer une liste de dévise (euro, yen, dollar) et y accéder à partir d'une liste déroulante à choix unique pour ensuite formater un montant. Si je chosi euro ou dollar alors je veux que le montant (input)soit écris avec 2 décimales à la fin, sinon en cas de choix du yen, je voudrais qu'il y ait 3 décimales. Je n'arrive pas à créer une classe qui me permettrait de formater le montant en fonction de la devise choisie. Quelqu'un peut il m'aider? Merci pour vos reponses

value="#{offreEligibleBean.currencyNameList}"/>
</cgit2:selectOneMenu> <br> |
le formatage est géré par cette classe

Quelqu'un pourra t'il donc me dire comment faire pour afficher le montant formatté une fois la la dévise choisie?
Merci
