[Zope3-Users] Two content objects' simultaneous adding

[baiju m]

I have two content objects (both are containers) but I cannot add one
to another as give here :

    def create(self, data):
        square = Square()
        square.name = data['name']
        square.description = data['description']
        company = Company()
        company.name = data['companyname']
        company.description = data['companydescription']
        square['Comp1'] = company
        ...
        return square

It was working in 3.2, now NotYet error is coming in 3.3. Here is the traceback:

NotYet: <websquare.square.company.Company object at 0x41b6016c>

I tried to override CreateAndAdd like this:

    def createAndAdd(self, data):
        square = Square()
        square.name = data['name']
        square.description = data['description']
        event.notify(ObjectCreatedEvent(square))
        square = self.context.add(square)
        self._finished_add = True
        company = Company()
        company.name = data['companyname']
        company.description = data['companydescription']
        chooser = INameChooser(square)
        name = chooser.chooseName('Company', company)

        square[name] = company
        ...
        return square

And this worked, but is it necessary to override createAndAdd for this?
(INameChooser could have been used in the earlier case also)

Thanks,
