Я делаю аналогично этому ответу:
https://stackoverflow.com/a/32264748/6737670
->add(‘dependsOn’, ‘entity’, array( ‘class’ => ProductOption::class, ‘attr’ => array(‘class’ => «form-control», ‘multiple’ => true), ‘required’ => false, ‘multiple’=> true, ) );
Но при загрузке формы я получаю ошибку

Почему это так?
Версия сонаты из composer.json:
«соната-проект / доктрина-орм-админ-связка»: «^ 2.2»,
Symfony:
«symfony / symfony»: «^ 2.8»,
Я пробовал разные способы. Не могу найти нормальный учебник, как это сделать.
