4204	Admin interface attempts to save null to fields not in 'fields': list	david@…	nobody	"Admin appears to attempt to save NULL to fields that are not shown in the Admin interface?

Here is an example model that doesn't work. Trying to update a record using Admin will crash with 

""Data truncated; NULL supplied to NOT NULL column 'nlgroup' at row 1""
