WHERE IN not working

I'm going by the docs, trying to get a WHERE IN type of query working with the query builder.

I've got a flat array of IDs, e.g. something like this:

$IDs = array( 228052, 265635, 344498, 391761, 329203, 317911, 305961, 299939, 249429, 344706 );

I've tried the following ways to get this working:

• using the Expr class:

$qb->add( 'where', $qb->expr()->in( 'c.id', ':IDs' ));
$qb->setParameter( 'IDs', $IDs );

• alternatively:

$qb->add( 'where', $qb->expr()->in( 'c.id', $IDs ));

• even direct DQL:

$qb->where( 'c.id IN (:IDs)' );
$qb->setParameter( 'IDs', $IDs );

The generated DQL looks fine:

SELECT c FROM MyEntity c WHERE c.id IN('228052', '265635', '344498', '391761', '329203', '317911', '305961', '299939', '249429', '344706')

But when I call execute() on that query, all these variations give me the following error:

Expected argument of type "Doctrine\ORM\QueryBuilder", "array" given
