#21259: Wizard sets queryset instead of instance on InlineFormset
-----------------------------------+-----------------------------------

Type: Bug | Status: new

Severity: Normal | Keywords: wizard, InlineFormSet

-----------------------------------+-----------------------------------
Because {{{InlineFormSet}}} subclasses {{{BaseModelFormSet}}}, the wizard
thinks it's like any {{{BaseModelFormSet}}} and incorrectly initializes
the form by setting the form's {{{queryset}}} instead of the form's
{{{instance}}}. An {{{InlineFormSet}}} needs to have its instance set to
the parent model object instead.
Currently, attempting to set {{{self.instance}}} for the
{{{InlineFormSet}}} in the wizard's {{{get_form_instance}}} results in an
{{{AttributeError}}} saying "object has no attribute 'none'" as the wizard
attempts to set the form's queryset (instead of instance) with it's
{{{self.instance}}}.
I have a fix to propose here:
