We're using Jboss 4.0.5.GA with Seam 1.1.6.GA.
I have an XHTML page which contains a doctype declaration as normal:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
When the page gets rendered, the doctype has been stripped out.
I need to have it in the generated source as the browser does not render correctly otherwise.
Try asking this on the facelets list - a purely facelets q :)
