How that works with inheritance entity about lexikformfilterbundle

Hi, you should not provide an abstract class as data_class because of the Form framework will try to create an instance of the data_class if no data object is provided when the form is created. And the bundle don't need a data_class to work, in my case most of time I set the data_class to null for a form type that is dedicated to filtering.

@cedric-g thx for reply,

with

public function setDefaultOptions(OptionsResolver\OptionsResolverInterface $resolver)
    {
        parent::setDefaultOptions($resolver);

        $resolver->setDefaults(array(
            'data_class' => null,
        ));
    }

that's work, but the field "Type" who corresponding to my discriminator map does'nt work

so i've trying to add a apply_filter like that :

$builder
            ->add('type', 'filter_choice', array(
                'choices' => $typeChoices,
                'apply_filter' => function(LexikFormFilterBundle\Filter\Query\QueryInterface $filterQuery, $field, $values)
                {
                    $filterQuery->getQueryBuilder()->add('where', 'u.type = :u_type')->setParameter(':u_type', $values['value']);

                    return $filterQuery;
                }
            ))

but i got this error :

An exception has been thrown during the rendering of a template ("[Semantical Error] line 0, col 58 near 'type = :u_ty': Error: Class LIG\Bundle\UserBundle\Entity\User has no field or association named type")

i've same error with or without the apply_filter

thx for your help

                'apply_filter' => function(LexikFormFilterBundle\Filter\Query\QueryInterface $filterQuery, $field, $values)
                {
                    $filterQuery->getQueryBuilder()->add('from', 'LIG\Bundle\UserBundle\Entity\User'.$values['value'].' '.$values['alias']);
                    return $filterQuery;
                }
