2169	"""Please correct the error below."" With No Shown Errors"	tyson@…	anonymous	"When a class has a field that isn't shown in the admin interface but must not be blank, it's impossible to add a new one. You get a cryptic ""Please correct the error below."" message with no shown errors. The error message should probably say something about a hidden field.

Here's a sample model to reproduce this bug:

{{{
class Foo(models.Model):
	title = models.CharField(maxlength=100)
	url = models.URLField()

	class Admin:
		fields = (
			(None, {'fields': ('title',)}),
		)
}}}
