Adding Validation Errors in an array without a data_class. On line 64 and 68 i tried both `addViolationAtSubPath` and `addViolationAtPath` to get the error to show on the relative fields, but they always show at top of form. How can i do this?

MyFormType.php

<?php
namespace MyProject\Bundle\WebBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Validator\Constraints\Callback;
use Symfony\Component\Validator\Constraints\NotBlank;
use Symfony\Component\Validator\ExecutionContext;
use Symfony\Component\Validator\Constraints\Date;

class ExtraDataType extends AbstractType
{


    /**
     * {@inheritdoc}
     *
     * @param \Symfony\Component\Form\FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        parent::buildForm($builder, $options);

        $builder
                ->add('name', 'text', array(
                    'required' => true
                    )
                )
                ->add('choicefield', 'choice', array(
                        'required' => true,
                        'expanded' => true,
                        'choices' => array(
                            'a' => 'A',
                            'b' => 'B',
                            'c' => 'C'
                        )
                    )
                )
                ->add('field1', 'text', array(
                        'required' => false
                    )
                )
                ->add('field2', 'text', array(
                        'required' => false
                    )
                );


    }

    /**
     * @param OptionsResolverInterface $resolver
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $proceeds = new Callback(array(
            function($data, ExecutionContext $context) {

                if ($data['choicefield'] == 'c') {

                    if ( ! isset($data['field1']) || empty($data['field1'])){
                        $context->addViolationAtSubPath('field1', 'Required!!', array(), null);
                    }

                    if ( ! isset($data['field2']) || empty($data['field2'])){
                        $context->addViolationAtSubPath('field2', 'Required!!', array(), null);
                    }

                }
            }
        ));

        $resolver->setDefaults(array(
                'constraints' => array($proceeds)
            ));
    }
}

A little tip for debugging such errors faster in the future:

• Log the property path of the error you are interested in in ViolationMapper:38 (e.g. var_dump($violation->getPropertyPath()))
• Log the property path of the field you would like it to be attached (e.g. var_dump((string)$form->get('myField')->getPropertyPath()))

Note the difference.

I'll be working on something to facilitate this somewhen.
