This is very strange:

  It is true that a "FactoryDispatcher"
  ("App.FactoryDispatcher.FactoryDispatcher") does not have
  security assertions. But usually, it does not have a
  "title_or_id" either. Therefore, it should not be relevant
  with respect to "title_or_id" access that it lacks security assertions.

  Maybe, it is a bug introduced with the security tighening introduced
  in Zope 2.7.3 (there was some discussion about such a bug in the
  mailing list (zope-dev, I think)).

You can try to add a "__role__ = None"
and maybe a "__allow_access_to_unprotected_subobjects__ = 1"
to the "FactoryDispatcher" class (--> "App/FactoryDispatcher.py")
to see whether the problem disappears.
These two attributes will provide security assertions for the

Your "header/manage_main" DTML Method seems a bit strange, too.
Why does it use a "dtml-in" and in it a "dtml-with" and in it
access to "title_or_id". This is somewhat unexpected in the
add form of a ZClass.
