You can add a custom setupWidgets method in the sub form which
disables the context adaption.
Stephan and I duscussed this during development, I think we
should add the hook into the form. He thinks not. But I guess
we have to discuss this once again.
Here is the method for context less forms:
def updateWidgets(self):
self.widgets = zope.component.getMultiAdapter(
(self, self.request, self.getContent()), interfaces.IWidgets)
self.widgets.ignoreContext = True
self.widgets.ignoreReadonly = True
self.widgets.update()
> def create(self, data):
> r = Restaurant()
> r.name = data['name']
> r.description = data['description']
> r.address = data['address']
> return r
>
> def add(self, object):
> self._name = object.name
> self.context[self._name] = object
> return object
>
> def nextURL(self):
> return absoluteURL(self.context[self._name], self.request)
