Please disregard this, this wasn't the problem. This initially worked but when I added the jstl conditional checking it stopped so naturally I blamed it on the jstl. I rolled back everything and it was still not working. The problem was the method signature used to take a Long parameter but was changed to long. The paramter being passed to the page was: | <param name="groupID" value="#{cameraAccessor.cameraGroupID}" | converterId="javax.faces.Long"/> Using a javax.faces.Long converter. I guess autoboxing isn't supported in this matter. There was no way I could see in the Seam Debug page to indicate this problem. It was only a matter of going through all elements that I discovered this. S.D. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4099075#...
