Ah, ok, now I think I got you. Is the the property 'workfield' of the 
object you're quering for of type RELATION_HAS_ONE (so only refers to 
one workfield)?  If so, try this:

// this is working for me
$query->equals('workfield', $filter->getWorkfields());

// if the workfield property is n_n, try this:
$query->in('workfield.uid', $filter->getWorkfields());
