Are you sure that there is no map:mount in whole call stack? Is your sitemap managed by Servlet
Service Framework?

I think it's shared responsibility but the most significant part must be taken by me.
I gave you description of current state of our code to help you get involved but only if you
to, of course. Nevertheless, I really, really want to avoid one-man shows as we both know
that it's
not how open source works. I can fix this myself (as soon as time permits) but this will not
situation that I and Daniel to some extent will have a any clue about this code.

Implementing this sitemap scope is just a must in order to support old Cocoon code.

In order to help you with migration I must get some details about your current setup and structure
of application.

It's your turn to be more informative, dear ;-)
Paste this ugly stack trace, it may really help me to understand what's the real cause of
troubles. Take into account most (I haven't tested every single one) samples work with current
so it's something specific to your application/setup.

Most important: can you reproduce this behaviour when developing some simple test based on
