>> Don't think so. You have document() function somewhere,

What I can't figure out is why the page renders at all! When I start up
Cocoon, my first request to the page works.
Then the next 1-3 requests return the null pointer exception, followed by 1
good request, then nulls again, then 1 good request, etc, etc, etc.
I'm requesting the exact same URL, which maps to the exact same matchers in
the sitemap, and iterates over exactly the same data each time 8-( Hence
why I thought it may have something to do with caching.
>> What cocoon version do you have?
Latest Binary Distribution.

Uh... I didn't chance any source or configuration, other then switching
over to Saxon. To switch over I replaced the Xalan jars with Saxon 6.5.1
jars.

After more extensive debugging, I'm seeing an error in the Cocoon error log
pointing at one of my XSL sheets -- but I'm not understanding the error.
I've included the error message, stack trace, and XSL sheet below.
Essentially what the style sheet does, is strip off the "xsp:page" node that
gets stuck into a page generated from an XSP page. Perhaps someone has a
better idea of how this can be done.
Thanks,
Mike
