4.2.2 upgrade from 4.1 and images location issue

Question

I've just upgraded from 4.1 to 4.2.2, and am having an issue with the referenced location of the images directory (/i/) resources. I am running apex listener on weblogic server, and have copied the new images into the i.war that I use. I have an unusual reverse proxy situation where my base URL includes a path, i.e., https://www.my.website.com/mysite/ is the URL that the proxy returns to the user, so my APEX addresses look like https://www.my.website.com/mysite/apex/f?101:1:::::, and my image directory references get put together like https://www.my.website.com/mysite/i/image.jpg.
However, with the upgrade, one of the things that popped up was all of the datepickers in my application were changed to classic datepickers, which worked and displayed fine. When I change them to the new datepicker, the small calendar image doesn't show next to the field (red x), and when I look at the properties of the image, it's URL is https://www.mywebsite.com/i/asfdcldr.gif (no "/mysite/" path offset). ALL of the other images directory references seem fine, but not this. Has 4.2.2 changed how it composed the #HOST# when it's generating these new controls (same result when I make a datepicker from scratch)? Why do all of my other images directory references work? The only other problem that I'm seeing is that my charts no longer work, either. I used to have to hardcode my URL into the XML of the charts for them to work, but I don't see the URL referenced in the code anymore. Not sure if that's related, but that has always been an issue with my reverse proxy situation (I don't control the proxy server).
Thanks in advance for any light anyone can shed on this,

Hi Warren,

With APEX 4.2, we've changed how charts are initialized to be JavaScript only, and as part of the changes, we no longer expose the region source for charts. See *4.8 Updated AnyChart Flash Charts* in the APEX 4.2 Release Notes, here: http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35121/toc.htm#CACEJBCD. So it's no longer feasible to hardcode a reference to your URL in the region source for a chart. If you have a reverse proxy, the CGI environment variables REQUEST_PROTOCOL, HTTP_HOST, SERVER_PORT, and SCRIPT_NAME, have to be correctly set to the public facing web server and not to the internal forwarding connection. If you execute the following query in SQL Workshop on your APEX instance, do you see the settings for the public facing web server?
select owa_util.get_cgi_env('REQUEST_PROTOCOL'), owa_util.get_cgi_env('HTTP_HOST'), owa_util.get_cgi_env('SERVER_PORT'), owa_util.get_cgi_env('SCRIPT_NAME') from dual;Regards,
