url parameters in Formwizard

[Alexander Ayasca Esquives]

I'm using the development version of django-formwizard (https://docs.djangoproject.com/en/dev/ref/contrib/formtools/form-wizard/), how could I send parameters through a url to a wizardview ? 

this is mi url:   r'^buscar/control/(?P<ninopk>\d+)', form_control_nino.as_view([ ControlForm,], )

thanks
