Symfony3 Form EntityType

I am using Symfony3, getting following error when creating form for EntityType::class

My entity namespace Project\CoreBundle\Entity\CountryEntity

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('name', TextType::class, ['label' => 'Name *', 'attr' => ['data-help'  => 'enter language name here.']])
        ->add('iso', TextType::class, ['label' => 'ISO *', 'attr' => ['data-help'  => 'enter language code here.']])
        ->add('defaultLanguage', EntityType::class,
            array(
                'class' => 'Project\CoreBundle\Entity\CountryEntity'
            )
        )
        ->getForm();
    ;
}

Throws Catchable Fatal Error: Object of class Project\CoreBundle\Entity\CountryEntity could not be converted to string

Any help will be useful, thanks

as EntityType is an extension of ChoiceType, it needs to know how to render your entity to the form. If you do not pass any information it will try to use the __toString() method. If it is not defined, you'll get this error.

Instead of implementing __toString(), you may specify the choice_label option for your field, which should be a path specification to a property, that should be shown. For example, your CountryEntity class may have a name property:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('name', TextType::class, ['label' => 'Name *', 'attr' => ['data-help'  => 'enter language name here.']])
        ->add('iso', TextType::class, ['label' => 'ISO *', 'attr' => ['data-help'  => 'enter language code here.']])
        ->add('defaultLanguage', EntityType::class,
            array(
                'class' => 'Project\CoreBundle\Entity\CountryEntity',
                'choice_label' => 'name'
            )
        )
        ->getForm();
    ;
}

See also EntityType's documentation at http://symfony.com/doc/current/reference/forms/types/entity.html.

Best regards
