symfony2 form error

问题

The form's view data is expected to be of type scalar, array or an instance of \ArrayAccess, 
but is an instance of class Ecs\CrmBundle\Entity\Customer. 

Is the error I get in my browser..

FORM CODE:

<?php

namespace Ecs\CrmBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class CustomerDefaultConfigType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
            ->add('customerStatus')
            ->add('tags', null, array('multiple' => true, 'property' => 'tag_name'))
        ;
    }

    public function getName()
    {
        return 'ecs_crmbundle_customerdefaultconfigtype';
    }
}

and the controller Action:

<?php

namespace Ecs\CrmBundle\Controller;

use Ecs\CrmBundle\Entity\CustomerDefaultConfig;
use Ecs\CrmBundle\Form\CustomerDefaultConfigType;
    public function newAction()
        {
            $entity = new CustomerDefaultConfig();
            $form   = $this->createForm(new CustomerDefaultConfigType(), $entity);

            return $this->render('EcsCrmBundle:CustomerDefaultConfig:new.html.twig', array(
                'entity' => $entity,
                'form'   => $form->createView()
            ));
        }

This is using symfony2.1 with composer... Any ideas on how to get this working?

回答1:

Since the last form refactoring, you have to specified the data_class in the setDefaultOptions method in your type.

See here (search for data_class).
