Symfony2 DQL on Fos Userbundle entity - symfony

Question

I'm implementing a search on a website and for simplicity i've decided to create a class that does the hard work.
Basically my class takes the EntityManager and the Entities in which i want to search and creates the DQL and executes the query. For normal entities this works totally fine but when i pass the User entity (Extended from fos user bundle entity) i get this error :
[Semantical Error] line 0, col 139 near 'last_login LIKE': Error: Class Soundmerger\UserBundle\Entity\User has no field or association named last_login
The dql query generated seems fine and as it works for the other entities i doubt it comes form there.
Here is my Search class :
use Doctrine\Common\Util\Debug;
use Doctrine\ORM\EntityManager;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Query;
class Search {
private $em;
private $searchables;
public function __construct(EntityManager $em, ArrayCollection $searchables){
$this->em = $em;
$this->searchables = $searchables;
}
public function search($query){
$words = explode("+", $query);
$qb = array();
$results = array();
foreach($this->searchables as $qNumber => $searchable){
$qb[$qNumber] = "SELECT s FROM $searchable s ";
$columns = $this->em->getClassMetadata($searchable)->getColumnNames();
foreach($words as $i => $word){
foreach($columns as $k => $column){
$string = "s.$column LIKE '%$word%'";
if($i == 0 && $k == 0){
$qb[$qNumber] .= "WHERE $string";
} else {
$qb[$qNumber] .= "OR $string";
}
}
}
$res[] = $this->em->createQuery($qb[$qNumber])->getResult(Query::HYDRATE_SIMPLEOBJECT);
}
return $this->formatSearch($res);
}
private function formatSearch($results){
$formatedResult = array();
foreach($results as $k => $result){
if(!empty($result)){
$formatedResult[$k]["type"] = get_class($result[0]);
$formatedResult[$k]["data"] = $result[0];
}
}
return $formatedResult;
}
}
And my Controller for the search :
/**
* #Route("/search/{query}")
* #Template()
*/
public function indexAction($query)
{
$em = $this->getDoctrine()->getManager();
$searchables = new ArrayCollection(
array(
"SoundmergerUserBundle:Professional",
"SoundmergerFaqBundle:Faq",
"SoundmergerUserBundle:User",
));
$search = new Search($em, $searchables);
return array('search' => $search->search($query));
}
And finally my user entity :
/**
* #ORM\Entity
* #ORM\Table(name="fos_user")
* #AttributeOverrides({
* #AttributeOverride(name="emailCanonical",
* column=#ORM\Column(
* name = "emailCanonical",
* type = "string",
* length = 255,
* nullable = true
* )
* ),
* #AttributeOverride(name="email",
* column=#ORM\Column(
* name = "email",
* type = "string",
* length = 255,
* nullable = true
* )
* ),
* #AttributeOverride(name="username",
* column=#ORM\Column(
* name = "username",
* type = "string",
* length = 255,
* unique = false
* )
* ),
* #AttributeOverride(name="usernameCanonical",
* column=#ORM\Column(
* name = "usernameCanonical",
* type = "string",
* length = 255,
* unique = false
* )
* ),
* })
*/

Any ideas on why this is only happening with the user entity (it must be due to the inheritance but i can't seem to find a way round it)
btw : its a university project so the idea of using an external bundle for the search is not really possible.
Thanks for any help
