I think you can do this with ERXExistsQualifier and a Not qualifier.

Hey all,
Maybe I missed something but is there
a way to construct a qualifier that check that a toMany relationship is
empty? Simply putting in "toMany =%@, new NSArray(new Object[] {NSKeyValueCoding.NullValue}doesn't
do it because it tries to check across the join table which results in
no objects being found.
