Extra MultiWidget fields in Inline in Admin are validating when left blank

Can you please provide more specific details? The only change made in [7517] was to the MultiWidget? which would indicate the problem still exists with it. You say "extra fields" and I am not sure what exactly you mean?

Extra fields as in the extra blank records which are displayed for TabularInline? or StackedInline? editing:

class TextRangeInline(admin.StackedInline):
	model = TextRange
	extra = 3
	listdisplay = ('start', 'end',)

Start and End are MultiValueFields? stored as Integers, and edited through a MultiWidget?.

So I would imagine that the problem would net occur when the Inline contains no MultiWidget? fields.

I can't reproduce the problem. Are start and end required fields? If not then make sure you have have marked them as not being required. I am beginning to wonder if the bug fix has uncovered a problem in your code. If you can post some more specific details that would be nice otherwise I will close this ticket. For the record listdisplay isn't even a valid option. Neither does list_display even mean anything for an inline. ;)

You are correct. Sorry for the false alarm.

My MultiWidget? had a Select Widget, and the first line of my choices was (None, '------------'). This worked before. None was being recognized as no selection. Now, after the MultiWidget? fix, None was being recognized as a selection. I changed the first line of choices to (, '------------'), which corrected the problem.

Not sure how listdisplay got in there originally.

WikiFormatting screwed that up. Rather, first choice was changed to:

('', '------------')
