-------------------------------------------------------------

StyleAndScriptIdentifier wraps all inline JavaScript in CDATA, but only if 
their type is "text/javascript".
Thus your template header contribution stays untouched.

wicket-ajax-jquery.js then uses the following to parse the header contribution:

    parser.parseFromString(text, "text/xml");

This fails, because entity   is not defined in XML. If we change the 
second parameter to "text/html", parsing of your template will work.

We'll have to check whether that change is safe for all browers though, I've 
just tested it in Firefox only.

> On initial page load, everything is fine - the TestPanel is parsed correctly 
> and displayed.  Hit the link to reload the TestPanel via AJAX - wicket is 
> getting hung up on the non breaking space {code:html} {code} inside the 
> template/script definition.
