Description
I have a ManyToManyField that I want to be able to leave blank but if I do that I get this error:
"instance needs to have a primary key value before a many-to-many relationship can be used"
I only get that error in the AdminCP though.

Sorry, the error was caused by a problem in my "pre save" trigger. Ignore
