Symfony2: ни одно из свойств … не существует и не имеет открытого доступа к PropertyAccess, но да, оно существует

В моем приложении symfony2 я клонирую объект и его коллекции.
Я использую класс PropertyAccess для установки значений свойств, но мне кажется, что мне не хватает метода доступа для добавления элемента в коллекцию.

РЕДАКТИРОВАТЬ: я понял, PropertyAccess также может вызвать метод добавления

Мой код:

        $collectionNames = array('tags', 'objectCategories', 'groups');
foreach ($collectionNames as $collectionName)
{
$collection = $accessor->getValue($this, $collectionName);
$this->$collectionName = new ArrayCollection();
foreach ($collection as $element)
{
$accessor->setValue($this, $collectionName, $element);
}
}

Я получаю следующую ошибку:

Neither the property "objectCategories" nor one of the methods "addObjectCategory()"/"removeObjectCategory()", "setObjectCategories()", "objectCategories()", "__set()" or "__call()" exist and have public access in class "AppBundle\Entity\FoodAnalytics\Recipe".
500 Internal Server Error - NoSuchPropertyException

Но метод addObjectCategory существует и имеет открытый доступ, как вы можете видеть в моем классе

Как я могу решить это?
Большое спасибо !

РЕДАКТИРОВАТЬ: весь класс рецептов:

Решение

вы можете сделать это,:

$var = $acc->getValue($this,$index);
$var->addElement('element');
$acc->setValue($this,$index,$var);

это будет работать нормально

[редактировать]

Мой код будет работать с вашим реальным кодом, так как вы используете ArrayCollection в своем классе.

когда вы получаете значение с

getValue($this,$index)

, он возвращает вам объект ArrayCollection, у которого уже есть метод addElement, так что это должно работать нормально.

Другие решения

ОК, ошибка была в том, как я использовал аксессор.
Следующее редактирование решает проблему:

        foreach ($collectionNames as $collectionName => $clone)
{
$collection = $accessor->getValue($this, $collectionName);
$this->$collectionName = new ArrayCollection();
$newCollection = new ArrayCollection();
foreach ($collection as $element)
{
$newElement = $clone ? clone $element : $element;
$newCollection->add($newElement);
}
$accessor->setValue($this, $collectionName, $newCollection);
}
