[TYPO3-commerce] missing method getManufacturerTitle in class.tx_commerce_db_product.php ?

[media.res | Alex Widschwendter]

hi,

the product class offers a method to get the manufacturer title:
function getManufacturerTitle() {
      	if ($this->getManufacturerUid()) {
      		return 
$this->conn_db->getManufacturerTitle($this->getManufacturerUid());
      	}
      	
      }

but the function doesn't exist in class.tx_commerce_db_product.php.

so i wonder how this could be?

thx for some insight!

cheers alex
