Turn off html character escaping
I'm trying to get facelets to render my css files (especially neet to
get the url(#{facesContext.ex
Reccomended by some of the guys on the facelets mailing list, I first tried
to do <f:view contentType="text/css">...</f:view>
This went badly, because the html renderer kit for myfaces doesn't
support this contentType. It only support a small set of content types
defined;
private static String HTML_CONTENT_TYPE = "text/html";
private static String TEXT_ANY_CONTENT_TYPE = "text/*";
private static String ANY_CONTENT_TYPE = "*/*";
private static String APPLICATION_XML_CONTENT_TYPE = "application/xml";
private static String TEXT_XML_CONTENT_TYPE = "text/xml";
private static String XHTML_CONTENT_TYPE = "application/xhtml+xml";
Tried then to use the */* - this went OK - the problem now however is
that either facelets or
myfaces escapes special characters in the css files:
The following perfecly valid css selector:
h2 {
font-family: Arial, "Arial CE", "Lucida Grande CE", lucida,
"Helvetica CE", sans-serif;
}
is escaped with
h2 {
font-family: Arial, "Arial CE", "Lucida Grande CE",
lucida,
"Helvetica CE", sans-serif;
}
rendering the generated css as invalid
Is there a way to turn off html entity character escaping for a
particular view?
Thanks,

BTW, you should be able to add a
<c:set var="cp" value="#{facesContext.externalContext.requestContextPath}/>
to your page so you can just write:
body {
background:
url(#{cp}/images/background.jpg);
}

I simply solved it by doing
<f:view xmlns:f="http://java.sun.com/jsf/core"
contentType="*/*">
<f:verbatim> ....thecss ...</f:verbatim>
</f:view>
It didn't htmlescape my special characters, and now my CSSS is valid
again + I have the power of EL expressions inside CSS
I can now simply use EL expressions to get all the images inside my CSS
files aligned with the context path, which was my main intention;
body {
background:
url(#{facesContext.externalContext.requestContextPath}/images/background.jpg);
}
Probably not the most obvious use-case, but EL expressions offer
functionality which sometimes could be
used beyond the scope of XML-type languages.

The issue would be that MyFaces is creating an HtmlResponseWriter
even though it's not HTML. Hard to blame it, though. The general
intent here is for XML-type languages.
In this scenario, I'd probably recommend that Facelets
specifically intercept text/css and text/plain to create
an internal PlainTextResponseWriter, one that throws
exceptions on calls to startElement(), for example, but
passes writeText() straight to write().
