Thanks for the reply. In this article Rick Hightower explain how to make compile-time tag, which doesn't work for my requirements. It's not difficult to turn them into render-time tags but I found easier to just use the rendered attribute. I've done a component which work like this : | <rw:pollquestion answerType="#{q.answerType}" | answerStyle="#{q.answerStyle}" | answers="#{q.answers}" | freeText="#{q.freeText}"> | <s:selectItems value="#{q.options}" var="opt" label="#{opt.text}"/> | </rw:pollquestion> | Type can be OPEN, MULTIPLE or SINGLE. Style is one of LIST, MENU, TICK_HORIZONTAL, TICK_VERTICAL. You get a list of POJO into answers if the type is not OPEN or a String in freeText. It works but it's a pain in the ass to write it. I finally decided to stick with facelets / rendered attribute. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4049623#...
