Pages don't always show when using cfinclude

Question

For our site we have a page template, a shell, that we use to
display pages. It uses a cfinclude to call the page into the
template:
<cfinclude page=#url.PageName#.cfm>
The link for that page would look like:
<a href="index.cfm?PageName=contact">
However, on a number of occassions, users click a link for a
page, and get the error "page not found". If they simply hit
refresh, the page shows up without a problem. The page is there,
and it works, but it just doesn't always show until refreshed. Of
course, most users don't know to refresh, and it's a pain to do
anyway.
Any ideas why this happens? Suggested solutions?
Thanks,
Tim

Answer 1

i use cfinclude constantly with no problem... when you get
the 404 page, right click, go to properties and see what page is
being called.
i doubt this would be an issue but try dropping the "url."
from variable... (never know). i usually misspell things like
"PageName" for the same reason (never know) so would be pgName or
something. i never use common words unless i have to in variables
and db fields.
love CF but it has got tons of weird bugs that you just have
to work around.
hope this helps....
