I found out what has been happening:

for some reason, the browser:addMenuItem was lacking the view element, so
the addform was not called.
Without the addform, it is not possible the fill all the attribute of the
object istantiated, so I got
the error about the name being void.

My fault, by all means.
Thanks for your support: learning Zope3 is tough, and while reading all
that's available we're still stumbling against many walls. The help of this
list is invaluable.

ciao
