here is the complete code : <h:commandButton value="#{msgs.update}" action="update" rendered="#{!empty contact.name}"/> | <h:commandButton value="#{msgs.createnewcontact}" action="addContact" rendered="#{empty contact.name}"/> | The second button works perfectly but pressing the first one does'nt produce anything :-( I checked the code with firebugs and the page doesn't contain errors :-( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3996180#...
