Portal scoped path and the html portlet?

Hello Everyone,

I am trying to use the portal scoped path in my html portlet to display an
html file in the resourceset. In the html portlet, I set it to manually
configured, and the URL is:

${Portal/Url/Resource/html/filename.htm}

But the html portlet shows "Runtime Error" in the title, and the text of "A
problem occured while rendering the portlet: HTML".

I have modified the html of the header portlet slightly to show a link to a
custom help file in a new window, and the URL used in the link tag is this:
${Portal/Url/Resource/html/help.htm}

That link works perfectly. If I replace the help.htm text in the browser
address bar with the "filename.htm" I am trying to use the html portlet, my
filename.htm page displays fine. The htm files I'm working with are in the
/data/html folder of my resourceset. If I change the html portlet settings
to use the URL of:
http://server_ip/ExpressPortal/resou...l/filename.htm that displays
fine. There must be something I don't have configured right, but I'm not
sure what.

The first URL above works fine with an Extend 5.2 project deployed to a
server running on Netware, but I can't get this to work with a new project
on Extend 5.2.1 running on a Windows server. Any suggestions?

Thanks!

Josh
