Matt,
Yes, these two lines are taken directly from within my perform method, and
make use of the example method I sent previously. They perform the styling
and make the text available to the view layer.
String content = getContent(getCurrentFormElement(req, map),
getStyleSheet());
req.getSession().setAttribute(CONTENT, content);
