Thanks Shane,
I know this is a configuration issue, either a wrong version of a jar file for something. It should be simple but it is driving me nuts. Do you know of a working example that uses s:hasRole?
I tried s:hasRole('admin') as follows and it throws the following exception when I hit that page. Is it using the same Seam taglib or do I have to add a new taglib?
<h:selectOneMenu value="#{switcher.conversationIdOrOutcome}" rendered="#{s:hasRole('admin')}" >

The documentation states that I have to use the following view-handler for this to work. If I add the component as follows to the the faces-config.xml file the pages will not load period.
<application>
| <view-handler>org.jboss.seam.ui.facelet.SeamFaceletViewHandler</view-handler>
| </application>
|

Exception (Is this using the wrong view-handler?):
