Erreur "javax.el.ELException: /default.xhtml: Property 'orderNo' not found on type com.datatable.Order"

**la vie bachiri** · 15/08/2012, 02h28

Bonjour,

J'ai implémenté un petit exemple de JSF.

J'utilise les jar de jsf-api, jsf-impl pour la version 2.1.7 + JSTL 1.2.

Lors de l'exécution de la page il donne ce message :

GRAVE: Error Rendering View[/default.xhtml]
