Sonata mongodb Admin-Bundle Filter durch Verweis

Question

Ich habe Dokument mit

/** @MongoDB\ReferenceMany(targetDocument="NewsTag") */ private $tags;

Beziehung.

In meinem Sonaten Admin möchte ich Liste nach Tag filtern. Ich versuche

$datagridMapper->add('tags', null, array(), null, array('expanded' => true, 'multiple' => true))

wie in Dokumentationen zu nutzen, haben aber einen Fehler

Could not load type "document"

Jeder weiß, warum?

UPD: Stack-Trace

Also, wenn Sie mit sonata_type_model filtern möchten wahrscheinlich ein Fehler hapens. Sie haben keinen ModelManager in ChoiceField. Aber man kann es in configureDatagridFilters wie diese manuell hinzufügen:

$datagridMapper 
     ->add('tags', null, [], 'sonata_type_model', 
      [ 
       'model_manager' => $datagridMapper->getAdmin()->getModelManager(), 
       'property' => 'name', 
       'multiple' => true, 
       'by_reference' => false 
      ]);
