3632	initial values lost when calling newforms.form_for_instance() with a custom form arg	ludo@…	Thejaswi Puthraya	"Initial values are lost when calling newforms.form_for_instance() with a custom form arg, eg

{{{f = forms.form_for_instance(u)}}} is ok

{{{f = forms.form_for_instance(u, form=MyCustomForm)}}} is not

The problem seems to be in DeclarativeFieldsMetaclass.__new__ where the 'base_fields' attribute gets wiped out when using a custom form class. A tentative patch, probably broken as my understanding of metaclass programming is nil, attached to this ticket.
