[Zope] ZClass permissions

[Tom Nixon]

I have created a ZClass and a new View called "Edit" which displays a
DTML Method containing an automatically generated Formulator form (both
situated inside the ZClass).

However when I create an instance of the ZClass then click the "edit"
view, I am prompted to enter my username and password.

If I change the DTML method to a simple "Hello World" message it works
fine, so it seems to be something to do with the Formulator form.

Obviously there is a permission problem somewhere, but where should I be
looking?
