php - Setting serialization groups for entity in other bundle with FOSRestBundle / JMSSerializerBundle -

i have simple rest api created using fosrestbundle, , returns serialized objects using jmsserializerbundle.

one of entities of bundle uses entity located in bundle.

i set serialization groups entity, not set aggregated entity json result empty.

i've followed documentation yaml groups configuration: http://jmsyst.com/libs/serializer/master/reference/yml_reference file seems unused (adding groups entity's properties has no effect, , don't errors if yaml file invalid).

here's code:

mycompany\mybundle\entity\meeting.php

class meeting {   /**    * @var point    *    * @orm\column(name="location", type="point", nullable=true)    * @jms\groups({"privatecontact"})    */   private $location;    // getters, setters , other stuff } 

acme\somebundle\orm\point.php

class point {   /**    * @var float    */   private $latitude;    /**    * @var float    */   private $longitude;    // getters, setters } 

mycompany\mybundle\resources\config\serializer\model.point.yml

acme\somebundle\orm\point:     properties:         latitude:             groups: ['privatecontact']         longitude:             groups: ['privatecontact'] 

mycompany\mybundle\controller\apicontroller.php

/**  * @rest\view(serializergroups={"privatecontact"})  */ public function getmeetingaction() {   ...    return array(     'status' => 'ok',     'meeting' => $meeting   ); } 

resulting json

"meeting":{"id":10,"date":"2015-07-16t19:20:00+0200","location":{}} 

for else has encountered problem, found view annotation in example did not work. however, if set serialization context correct group in controller action worked fine:

        $view->setserializationcontext(serializationcontext::create()->setgroups('site'));
