[jboss-user] [JBoss Seam] - Still confuse on usage of page param, help please!

Hi, I reviewed the seamspace example and tried to understand how and when to use page parameter, but I still get confused. After I commented the following page parameter codes, I couldn't find any performance difference(including bookmarkable page). Anybody can tell me the purpose of using page param and when need to use it. Thank you so much in advance! <page view-id="/comment.xhtml" login-required="true"> | <restrict/> | <!-- | <param name="name" value="#{selectedMember.memberName}"/> | <param name="blogId" value="#{selectedBlog.blogId}"/> | --> | <navigation from-action="#{blog.saveComment}"> | <redirect view-id="/blogentry.xhtml"/> | </navigation> | </page>and jsp link:<s:link view="/comment.seam" value="Add Comment" propagation="none"> | <f:param name="name" value="#{selectedMember.memberName}"/> | <f:param name="blogId" value="#{selectedBlog.blogId}"/> | </s:link> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4121949#...
