Symfony Entity Type, No lazy load - php

Question

I created a symfony entity form-type and used a QueryBuilder to get the entities.
My Querybuilder looks like this:
$qb = $this
->em
->getRepository('Namespace\Entity\Domain\Nic')
->createQueryBuilder('domainNic')
->join('domainNic.article', 'article')
->andWhere('article.category = :domainCategory')
->setParameter('domainCategory', Article::CATEGORY_DOMAINS)
->orderBy('article.title');
My form type definition below looks like this:
$builder->add(
'withTld',
'bootstrap_collection',
array(
'allow_add' => true,
'allow_delete' => true,
'add_button_text' => 'addtext',
'delete_button_text' => 'deletetext',
'type' => 'entity',
'sub_widget_col' => 5,
'label' => '***',
'options' => array(
'class' => 'Namespace\Entity\Domain\NIC',
'query_builder' => $qb,
'property' => 'title'
)
)
);
The result looks exactly as expected, but for every found record, Symfony doesn't use the data from the QueryBuilder. Instead, Symfony fetches the title for each record again.
Anybody knows a solution? I want Symfony to use the data from the QueryBuilder.

You will need an extra select line in you query builder:
$qb = $this
->em
->getRepository('Namespace\Entity\Domain\Nic')
->createQueryBuilder('domainNic')
->addSelect('article') // <---------------- THIS
->join('domainNic.article', 'article')
->andWhere('article.category = :domainCategory')
->setParameter('domainCategory', Article::CATEGORY_DOMAINS)
->orderBy('article.title');
