z3c.form does not support the lame IAdding pattern by default. That said, I feel inclined to add an "AddingAddForm" to the compatibility module but strongly discourage its use. > > def update(self): > > self.address = AddressAddForm(self.context.address, self.request) > > ## <---- Problem area > > You did not say what the problem was.

Right, you could use a sub-form just fine, since you do not need all the actions. But you will need to customize the widget creation to ignore the context. > > self.address.update() > > super(RestaurantAddForm, self).update() This reminds me; this needs to be the other way around, because you need to first create the parent object. > > def create(self, data): > > r = Restaurant() > > r.name = data['name'] > > r.description = data['description'] > > r.address = data['address'] Mmh, this will not work either, because the data will not contain the address object.
