WHERE LIKE doesn't work on JOIN SELECTs.

WHERE LIKE doesn't work on JOIN SELECTs.
Params are not passed to the query.

Reproduce code:

	public function addSearchTerm(Doctrine_Query $query, array $fields)
	{
		$phrase = $this->getRequest()->getPost('query');
		if(!empty($phrase) && !empty($fields))
		{
			$phrase = '%'. $phrase .'%';
			$searchString = array();
			$searchParams = array();
			foreach($fields As $field)
			{
				$searchString[] = "$field LIKE ?";
				$searchParams[] = $phrase;
			} 
			$searchString = implode(' OR ', $searchString);
			
			$query->andWhere($searchString, $searchParams);
		}	
	}

$this->addSearchTerm($query, array(
			'username',
			'email',
			'last_login_ip',
			'Data.title',
			'Data.first_name',
			'Data.last_name',
			'Data.company',
			'Roles.name'
		));

Result attached as screenshot.

Query produced is correct, however '?' are not replaced with params from the array.

Error message is:
