自定义分页器/ formfilter / buildquery不会将过滤器数据处理到查询中

$this->filterForm = new OrganisationFormFilter();
$this->filterForm->setTableMethod(\'retrieveMemberOrganisations\');
$this->filterForm->bind($searchParams);
$v = $this->filterForm->getValues();
$q = $this->filterForm->buildQuery($v);

$this->pager = new sfDoctrinePager(\'Organisation\', 50);
$this->pager->setQuery($q->orderBy(implode(\' \',$this->getSort())));
$this->pager->setPage($request->getParameter(\'page\',1));
$this->pager->init();

public function retrieveMemberOrganisations(Doctrine_Query $q){

    $rootAlias = $q->getRootAlias();
    $q->
    select(\"$rootAlias.*\")->
    addSelect(\'m.id, sc.id, cat.id, cat.number_key\')->
    innerJoin (\"$rootAlias.CurrentMember c\")->
    innerJoin (\"$rootAlias.Membership m\")->
    innerJoin (\'m.LatestMembership lm\')->
    innerJoin (\'m.MembershipSubcategory sc\')->
    innerJoin (\'sc.MembershipCategory cat\');

    return $q;

}
