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.

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,
"Posting", "fetchNullPostingForMonth", null);
To me this seems crude, but it does work. Is there a better way
though?
