Doesn't work

$groupIds = array(1, 2, 3);
$query = new Doctrine_Query();
$query->from('Deal d, d.Groups g');
$query->where('g.id IN (?)', $groupIds);

Does work

$groupIds = array(1, 2, 3);
$query = new Doctrine_Query();
$query->from('Deal d, d.Groups g');

foreach ($groupIds as $group_id)
{
  $where .= 'g.id = ' . $group_id . ' or ';
}

$where = substr($where, 0, strlen($where) - 4);
$query->where($where);

The example that doesn't work only returns one Deal record no matter how many are actually returned. When I do $query->getSql() and feed the sql right to the database, more than 1 row is returned. I will try and produce this in a test case and update here.
