hi, I actually in set the response to be HTML with "&INFO_FORMAT=text/html"
in fact the response type in the header is text/html in the request. I turned on firebug and I see the AJAX request and the response HTML is empty. However when I copy the URL and put it straight in the browser, it comes back with the correct HTML.
