What's the difference between putting @RequestParameter in a session bean and putting the param tag in pages.xml? When I put the param tag in pages.xml for a given page, why does the attribute show up the first time as attributeName=0 rather than no attribute? I understand that 0 is the value of the EL in the param tag, but how can I get it to ignore that when it's 0 or null? (I'm using s:link for the link to the page referenced in pages.xml. Before I even go to that page, the link rendered to that page contains pageName.seam?attributeName=0) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4003367#...
