Fix form rendering issue - portfolio

Wake uses Tomcat RPM provided by RedHat. Because of that, xalan is being
used in XSLT transformation instead of the Java runtime processor. As
the result, some XML tags are shortened. e.g., <Tag></Tag> becomes
<Tag/>. Because <Textare> is a little special than other HTML tags, I am
putting Javascript to remove the initial text from the page, those texts
are used to "trick" the xalan processor as work-around.
