I am using struts-layout from struts.application-servers.com on jboss. I use a collection tag with a pager and then when I click on the page 2 or whatever number u want I get a very beautiful blank page. I have no exception, no message in the jboss console. I set in the struts-config.xml the SortAction like this: <action path="/sort" type="fr.improve.struts.taglib.layout.sort.SortAction" scope="request" validate="false">
