Hi G,
That works if keyword was a single attribute to User.
However, in my case "keyword" is many. (e.g. user.keywords() returns NSArray<Keyword>)
Doing that generates an sql :
SELECT
t0.id FROM User t0 WHERE
t0.id is NULL
which is quite wrong.
And yes I'm using WOnder.

MM I think it should be something like... assuming you are using wonder
EOQualifier qual = User.TO_KEYWORD.eq(null);
NSArray<User> array = User.fetchUser(ec,qual,sortOrdering);
correct me if im wrong.
