Of course using Clay means a totally different layout technology, just like using Facelets. That's not necessarily bad (JSP sucks) but it may or may not be possible for you (JSP is unfortunately mandated for the project I'm currently on). In the email thread referenced by Volker I did suggest one possible solution while staying with JSP. It's a bit hacky but I don't see why it wouldn't work. See the last paragraph of my response here: http://www.mail-archive.com/users%40myfaces.apache.org/msg11991.html Regards, Simon PS: I hate top-posting!!
