Admin date widget not working on inlines until after validation failure

[Russell Keith-Magee]

Sample models.py:

class Publisher(models.Model):
   name = models.CharField(max_length=300)

class Book(models.Model):
   name = models.CharField(max_length=300)
   publisher = models.ForeignKey(Publisher)
   pubdate = models.DateField()

admin.py:

class BookInline(admin.TabularInline):
    model = Book

class PublisherAdmin(admin.ModelAdmin):
    inlines = [BookInline]

admin.site.register(Publisher, PublisherAdmin)

Test procedure:

1. Create a new publisher
2. Click the "Add a new book" button
3. Set the name of the book.
4. Press the today button. Nothing happens - the date doesn't populate the date field.
5. Press the calendar widget. Select a date. The date doesn't populate the date field.
6. Save the object. This should cause a validation error, as pubdate is a required field
7. Press the today button. It works!
8. Press the calendar widget. It works!

I've observed this using Safari 4.0.4, Firefox 3.5.7, and Chrome 4.0.249.49 (35163) beta on OSX 10.5.8.

From what I understand this happens because the event handlers of the admin date widget aren't correctly handled when adding inlines dynamically.

I think we could work around that by re-initializing the calendar widgets when adding a new inline as long as we don't have a better way to tell the widget not lose the event handler.

Added a workaround for the DateTimeShortcuts widgets, still a solution for the FilterSelect missing

Patch doesn't fix my manifestation of the problem, as they don't work on newly added inlines either (as I described in dupe #12835).

User error on my part, the patch does indeed work.

Now works with SelectFIlter

Appears to work fine in Firefox/Safari/Chrome; however still having problems with IE7.

still having problems with IE7.

User error, again. Works in IE7; after running test suite will check in.

(In [12454]) Fixed #12705 -- Date/time and select filter widgets now work again with newly added inline forms in the admin.
