Symfony2 Expected argument of type "object or array", "string" given

Question

I'm trying desperately to save the form with entity City OneToMany Anagrafic. I entered the "property_path" CityType the form and I returned error,

Expected argument of type “object or array”, “string” given

I do not understand what I'm doing wrong!

class Anagrafic
{
/**
 * @ORM\ManyToOne(targetEntity="City", inversedBy="anagrafics", cascade={"persist"})
 * @ORM\JoinColumn(name="city_id", referencedColumnName="id")
*/
private $city;
//..
//..
class City
{
/**
 * @ORM\OneToMany(targetEntity="Anagrafic", mappedBy="city", cascade={"persist"})
 */
private $anagrafics;
//...
//...
class CityType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('comune', 'hidden', array('property_path' => 'city.id'))
//..
//..
class AnagraficType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('city', new CityType())

EDIT: Sorry for the incomplete information, this is the exception:

CRITICAL - Symfony\Component\Form\Exception\UnexpectedTypeException:

        }
        $property = $this->elements[$i];

the problem was that when you pass a string or a number, symfony expects an object, so we need to implement a DataTransformer to turn a string into object and vice versa.

http://symfony.com/doc/master/cookbook/form/data_transformers.html

Problem solved! ;-)

Looks like propertyPath expects a object or a array. So this line is wrong:

$builder->add('comune', 'hidden', array('property_path' => 'city.id'))

You are passing city.id here and that shouldn't be a string. I'm not a Symfony user and not familiar with the FormBuilder so you have to lookup the manual how to use the property_path option.

Btw. this has nothing to do with doctrine 2, so it would be appropiate to delete that tag.

the fact is that if you do not use the "property_path", I receive this error:

An exception occurred while executing 'INSERT INTO City (city, zip, region_id, state_id) VALUES (?, ?, ?, ?)' with params {"1":"8094","2":null,"3":null,"4":null}:  SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'zip' cannot be null

Try to save a new entity City, but City is a list of cities already predefined and the relationship City OneToMany Anagrafic should not have to create a new entity! What is wrong?
