Hi
I developed portlet which generate file. But everything works ok in ie and opera (I get filname "all.pdf")
But on firefox filename looks like this "all.pdf," (with extra comma)

Why firefox add to filname extra ","?

I have in my configuration.jsp this code :

 <%
 LiferayPortletURL resourceURL = (LiferayPortletURL) renderResponse.createResourceURL();
 resourceURL.setPortletId(ParamUtil.getString(request, "portletResource"));
 resourceURL.setParameter("pdf_one", "true");
  
 %>

<a href="<%= resourceURL.toString()%>" alt="Save to xls"></a>
    <input type="button" value="PDF" name="save_to_xls">

And this in my class

in serveResource I have

  res.setCharacterEncoding("UTF-8");
                res.setContentType("application/pdf");
                res.addProperty(HttpHeaders.CACHE_CONTROL, "max-age=3600, must-revalidate");

                res.addProperty(HttpHeaders.CONTENT_DISPOSITION,"attachment, filename=all.pdf");

Thanks for help

Regards
