symfony2 entity field type error

Question

I haven't found any solid example on how to do this.

I have my entity Shield, which can have more than 1 ShieldTypes. What I want to do is, create a form that creates a new Shield with different Shieldtypes.

This is my code, I honestly don't know where is my error:

Error is:

Entities passed to the choice field must be managed
500 Internal Server Error - FormException

    }

    {
        $this->name = $name;
    }
    public function getName()
    {
        return $this->name;
    }
    public function setTitle($title)
    {
        $this->title = $title;
    }
    public function getTitle()
    {
        return $this->title;
    }   
}

It can be a little confusing but:

Shield entity (database)
ShieldTypes entity (database)
ShieldType form (abstracttype)

Thank you...

is the problem anywhere near return $repository->createQueryBuilder('t')->orderBy('t.id', 'ASC') ? — jonv1

So the problem was that I didn't create a repository. I created it (see code at the end) and I still got 'Entities passed to the choice field must be managed' error.

Then I set mutiple to true in:

$builder->add('types','entity',
                array(
                    'class'=>'Armory\SearchBundle\Entity\ShieldTypes', 
                    'query_builder'=> function(\Armory\SearchBundle\Entity\Repository\ShieldTypesRepository $repository){ 
                                    return $repository->createQueryBuilder('s')->orderBy('s.id', 'ASC');},
                    'property'=>'title', 
                    'multiple'=>true
                    )
                );

I hope someone finds this useful, cause if I had had this, it would been easier.

Code for my repository:

namespace Armory\SearchBundle\Entity\Repository;
use Doctrine\ORM\EntityRepository;

class ShieldTypesRepository extends EntityRepository
{
    public function getAll()
    {
        return $this->_em->createQuery('SELECT s FROM Armory\SearchBundle\Entity\ShieldTypes s')
                         ->getResult();
    }
}
