<s:button view="/home.xhtml" value="Home" propagation="none" image="#{request.contextPath}/img/house.png" rendered="#{identity.loggedIn}"/>

But in the view i want to evaluate if the currentUser is Administrator or an alternative could be, set two buttons and change the rendered attribute but i want to know how can i make something like rendered if identity.loggedIn and identity.hasRole('Administrator').
Also want to know how can a made something like rendered if not identity.hasRole('Administrator').
Thanx in advice guys!!
