17677	WizardView.get_form destroys 'instance' and 'queryset' from get_form_kwargs	Gary Reynolds	nobody	"In the case where the wizard author might like to populate the form with an existing model instance or formset from a queryset based through `get_form_kwargs` it get's destroyed by a call to `kwargs.update({'instance': self.get_form_instance(step)})` or `kwargs.update({'queryset': self.get_form_instance(step)})`.

While I can appreciate that there is already a way to populate this value by overloading the `get_form_instance` method, I don't think that we should be destructive of another way to achieve it. Additionally I find it less confusing if I can define all kwargs to be passed to my form/formset init method in one place (ie. in `get_form_kwargs`) rather than splitting this logic into two places.

I've attached a patch against r17511 which includes a test case."	Bug	closed	contrib.formtools	1.4-alpha-1	Normal	fixed			Accepted	1	1	0	1	1	0
