4920	newforms-admin TabularInline with ManyToManyField breaks	anonymous	Adrian Holovaty	"In the newforms-admin, if a model has an inline (I've had issues with StackedInline and TabularInline) and the model used in the inline has a ManyToManyField the admin breaks returning:[[BR]]
[[BR]]
Exception Value:  	'StackedInline' object has no attribute 'filter_vertical'[[BR]]
Exception Location: 	/home/code/django/contrib/admin/options.py in formfield_for_dbfield, line 114[[BR]]

It works fine if the ManyToManyField is commented out of the inline model temporarily.[[BR]]
The model with the ManyToManyField works fine in the admin on its own (not called as an edit inline).
