Mmm.....reading the email I think it is a bit confuse.

What I am really trying to do is:

class ISomeContent(Interface):
    some_field = zope.schema.List(title='Some Field',

value_type=zope.schema.Object(title=u'Some Field',

             schema=IOtherContent)
                                                             )

class SomeForm(formui.EditForm)
    fields = field.Fields(ISomeContent)

So yes, I am trying to get a new ObjectWidget to render a automatic
form of the schema attribute of the ObjectField, IOtherContent in this
case, in the modal window. That would be kinda a meta-form because all
what the modal window would do is to put all the fields back in the
main form so it could be processed by the main form class.

Sounds crazy? Any ideas?

Kind regards,
Fernando
