Hey
in 2.x you could do something like this:
'conditions' => array('parent_id' => $parent_id);
where $parent_id could be an int or null
and it would find parent_id that were null in the table
This approach does not work in 3.x. Is there a right way to do this in 3.x
where a field in an INT but can be null ?
