This is deep voodoo that I don't fully understand. To me, it appears
that what you get depends on how your __call__ was called...

The arguments vary dependign on whether:
-you were called from a bit of DTML
-traversed directly through a URL
-called from soem python you wrote

Maybe someone from DC could shed some light on 'the rules' or point us
to soem documentation?

cheers,

Chris
