I could fix part of my problem: The formtools formwizard doc states for the us of modelformsets:
'WizardView supports ModelForms <http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#module-django.forms.models> and ModelFormSets <http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#model-formsets>. Additionally to initial_dict <http://django-formtools.readthedocs.org/en/latest/wizard.html#formtools.wizard.views.WizardView.initial_dict>, the as_view() <http://django-formtools.readthedocs.org/en/latest/wizard.html#formtools.wizard.views.WizardView.as_view> method takes an instance_dict argument that should contain model instances for steps based on ModelForm and querysets for steps based on ModelFormSet.' For me this does not make to much sense: Why should I specify model instances / querysets for steps basend on ModelForm / ModelFormSet? In the case of ModelFormSet, FormView seems to prepopulate the formset with all model instances from the database, causing half of my error above. Why has this behavior been chosen? I don't get it... Nevertheless, to fix this I added 'instance_dict = {'third': Task.objects.none()}' to the JobWizard. Still half of the error persists: Upon submitting the final formwizard-form, the *last* form in the TaskFormSet produces a 'RelatedObjectDoesNotExist' error for Step ('Task has no step'), even though it was preset by 'get_form_initial'. All other forms are saved without a problem. So what is special about the last form in the formset?
