getcollection with joins using newquery not working

hi iam using xpdo in a project
the getcollection(’table’,$query) is not working and its not fetching other tables data when using with join
my code is
$rq=$b2b->newQuery(’Rfp’);
$rq->leftJoin(’UserProfile’,’Reseller’,’`Rfp`.`reseller` = `Reseller`.`internalKey`’);
$rq->leftJoin(’CompanyJobtype’,’Job’,’`Rfp`.`jobType` = `Job`.`jobId`’);
$rq->select(array(’Rfp.*’,’Reseller.firstName’,’Reseller.lastName’,’Reseller.mobile’,’job.jobType’));
$rfps=$b2b->getCollection(’Rfp’,$rq);
foreach($rfps as $rfp){
$a=$rfp->toArray();
print_r($a);
}

i tried with toQuery(); and the sql returning with toquery is perfect
but in the getcollection result other tables data in not fetched
more importantly the join conditions also not counting when getcollection is fetched

just to clarify i have extended xpdo to b2b
not sure what i missed

by looking at one topic http://modxcms.com/forums/index.php/topic,37872.0.html
i understood XPDO_OPT_HYDRATE_ADHOC_FIELDS should be set to true
but it was const OPT_HYDRATE_ADHOC_FIELDS = ’hydrate_adhoc_fields’;
what value i have to give now to make getcollection work here?

getCollection will not return objects represented by tables you have manually joined. This is what getCollectionGraph() is for.
