I had similar error messages when trying to create the login/error page using the layout jsp as template, so that the same theme can apply to the login/error page as well. I was able to do it in JBP 2.2 SP1. But in JBP 2.6.4, I got that the same error pointing to the "<p:theme " line. If I removed that line, the error message gone. But it also means no theme at all. I could get the theme if I hard coded the corresponding "<link rel" line. I wonder if the "<p:theme" tag now has an additional requirement for an jsp page.
