Actually... It looks like I could make up a Stateless bean, with scope=EVENT. That bean would be in scope for every single page request within the Seam application, right? So that bean would be present at every one. Then I could annotate a member of that bean with @RequestParameter. Alternatively, I could put @RequestParameter on a getter/setter pair, and the setter could do the logic needed. The advantage is that the method would only be called when the affiliateId parameter is actually set. I guess I'm trying to use a bean as a smart / light filter, which seems like it should be possible. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966210#...
