So you want non-logged in user to be able to change the locale as well ? For logged-in user you should change the preference (you don't have to do it using the portlet, nothing prevent you from creating your own action calling the identity service to update the preferred language) For non-logged-in user, you would have to define how you want to store the preferred locale (session probably) and adapt org.jboss.portal.core.aspects.server/LocaleInterceptor accordingly View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4029683#...
