problem with hidden pages

Hi,

I'm running a dispatcher site and I'd like to add a custom '404 error'
page to it. I've created a 404.xml file and put it in my xdocs
directory. The page shouldn't appear in the navigation menu so in my
site.xml I've added an entry without 'label' attribute:

    <error404 href="404.html" />

When I execute 'forrest run' the browser loads the URL
localhost:8888/404.html with no problem. However, when I run 'forrest'
and create a static site, the 404.html is not added to the site. Could
someone tell me how to add a hidden page to a static site, please?
I've googled the web with no luck.

Thanks in advance,

Vicent
