[jboss-user] [JBoss Seam] - Did this -- but not working (Re: Newbei question: Page navig

[zwu_ca]

Thanks for help -- this has been driving me crazy (more than 12 hours have been spent -- a newbie in Seam).

I think I did do this: Could you look at what's wrong with the navigation (I also include the related Java code). Your help will be much appreciated. 





<page view-id="/home.xhtml">
        
            
                <redirect view-id="/itemlist.xhtml"/>
            
        
        
    
    <page view-id="/itemlist.xhtml"  login-required="true" >
            
          <navigation from-action="#{hotelBooking.cancel}">
            <redirect view-id="/main.xhtml"/>
