13175	"""+ Add another [...]"" bug with final_attrs['id']"	rasca	Simon Meers	"When adding a new inline in the admin through ""+ Add another [...]"" the id of the inputs is different from what final_attrs.id says it should be.

For example when rendering a widget that prints final_attrs.id I get
{{{
id_sponsor_set-4-logo
}}}
but actually the id is
{{{
id_sponsor_set-3-logo
}}}

To make this clear (can't express myself clearly) you can try changing line 218 from django/forms/widgets.py to 

{{{
212	    def render(self, name, value, attrs=None):
213	        if value is None: value = ''
214	        final_attrs = self.build_attrs(attrs, type=self.input_type, name=name)
215	        if value != '':
216	            # Only add the 'value' attribute if a value is non-empty.
217	            final_attrs['value'] = force_unicode(formats.localize_input(value))
218	        return mark_safe(u'<input%s />' % flatatt(final_attrs))

218	        return mark_safe(u'expected id: %s <input%s />' % (final_attrs['id'], flatatt(final_attrs)))
}}}
and add a new inline through the link and check what's been printed with the id of an input inside the newly created inline
