[Zope3-dev] Form machinery and forbidden attributes

[Garrett Smith]

There's a bug in the form machinery where forbidden attributes are being
treated as missing attributes -- i.e. they're being displayed as if the
object didn't have the attribute. I believe the behavior in this case is
to display the field's default value.

I think the way to handle this is to let the ForbiddenAttribute error
pass through.

If no one has any objections to this approach, I'll make the change.
