Is there a more elegant way of trying to fetch null objects?
Currently I have an object 'Posting' with a fetch spec
'fetchNullPostingForMonth' with the qualifier '(objectIDPostingsForMonth =
nil)'
Then in my code I have:
NSArray results = EOUtilities.objectsWithFetchSpecificationAndBindings( ec
I forgot to mention that "objectIDPostingsForMonth" is a foreign key and the
relationship in the entity Posting is called "postingsForMonth"

In code, you can use EOKeyValueQualifier with a value of
NSKeyValueCoding.NullValue which is a substitute for null where null
cannot be used in Apple's frameworks.

What do you mean by "null objects"? Objects with a specific
attribute that is null? With a to-one relationship that has no
object in the destination? With a to-many that has no objects in the
relation? Something else?
