[Symfony] doSelectJoin - błąd Opcje

[janek9]

Mam glupi problem z ktorym nie moge dac rady. Mam takie 2 tabele w schema:

<

[PHP] pobierz, plaintext 
  tp_user_award:
    id:          ~
    id_award:    { type: integer, foreignTable: tp_award, foreignReference: id }
    is_blocked:  { type: boolean, default: False }
 
  tp_award:
    id:          { type: integer, primaryKey: true, autoincrement: true }
    award:       { type: integer, size: 4}
[PHP] pobierz, plaintext 

a w TpUserAwardPeer mam tak:

[PHP] pobierz, plaintext 
static public function getAwardFromUser($id)
	{
		$c = new Criteria();
 
		$c->add(self::ID_USER, $id);
		$c->add(self::IS_BLOCKED, False);
 
		return self::doSelectJoinTpAward($c);
	}
[PHP] pobierz, plaintext 

i w akcji tak:

[PHP] pobierz, plaintext 
public function executeIndex(sfWebRequest $request)
  {
	$award = TpUserAwardPeer::getAwardFromUser($this->getUser()->getGuardUser()->getId());
 
	$p = 0;
 
	foreach($award as $aw)
	{
		$p += $aw->getIdAward()->getAward();
	}
 
    $this->user_award = $p;
  }
[PHP] pobierz, plaintext 

pokazuje mi ze:

[PHP] pobierz, plaintext 
atal error: Call to a member function getAward() on a non-object
[PHP] pobierz, plaintext
