Peter, thanks for the reply. So if the action is selected, it means the group CAN perform it ? On the other hand there's this strange behaviour, if I access the page - which has two Portlet Bridge portlets - with an unauthenticated user, the portlets are referencing old urls. If the user is authenticated, they point to the right ones. Is this a cache problem ? Is there a way to clean the cache ? Anyway, the final goal is to hide the upper tab that points to the page if the user doesn't belong to a particular group. Thanks in advance.
