symfony - Doctrine OneToMany relationship error -

i trying set manytoone/onetomany relationships on objects in database using doctrine (2.2.3+) via symfony2 (2.3.0) , getting strange error. here relevant parts of objects (many attributes 1 product):

/**  * product  *  * @orm\table(name="product")  * @orm\entity  */ class product {     /**      * @var integer      *      * @orm\column(name="id", type="integer")      * @orm\id      * @orm\generatedvalue(strategy="auto")      */     protected $id;      ...      /**      *      * @onetomany(targetentity="productattributes", mappedby="product")      */     protected $product_attributes;      public function __construct() {         $this->product_attributes = new \doctrine\common\collections\arraycollection();     } }  /**  * productattributes  *  * @orm\table(name="product_attributes")  * @orm\entity  */ class productattributes {     /**      * @var integer      *      * @orm\column(name="pa_id", type="integer")      * @orm\id      * @orm\generatedvalue(strategy="auto")      */     protected $pa_id;      /**      * @var integer      *      * @orm\column(name="product_id", type="integer")      */     protected $product_id;      ...      /**      *      * @manytoone(targetentity="product", inversedby="product_attributes")      * @joincolumn(name="product_id", referencedcolumnname="id")      */     protected $product; } 

when run the

php app/console doctrine:generate:entities bundlename 

command following error:

[doctrine\common\annotations\annotationexception]                                                                                                             [semantical error] annotation "@onetomany" in property lvmount\lvmbundle\entity\product::$product_attributes never imported. did maybe forget add "use" statement annotation? 

i have looked through doctrine docs , don't see reference "use" statement manytoone/onetomany pairings. going on?

your annotations' syntax aren't complete.

you can see proper syntax doctrine annotation below.

/**  * @orm\********  */ 

so, in case should following.

/**  * @orm\onetomany(targetentity="productattributes", mappedby="product")  */ 

you want fix annotations in productattributes entity.
