26018	FormMixin.get_context_data calls get_form improperly after form_invalid	Chris Cogdon	Chris Cogdon	"In the fix for ticket #25548, the validated (and failed) form is now passed in as a parameter to get_context_data. In that code, self.get_form() is called unnecessarily, which will likely cause a performance and side-effect penalty equivalent or worse to validating the form twice.

Solution is to use the ""if x not in d"" pattern instead of setdefault.

I'll create a pull request."	Bug	closed	Generic views	1.9	Normal	fixed			Ready for checkin	1	0	0	0	0	0
