Disable backend validation for choice field in Symfony 2 Type

Question

Is it possible to disable backend (server-side) validation for the specified field?

Wnen Im trying to send form with dynamicly loaded options I get error \"ERROR: T

It's confusing but this behaviour is not really validation related as it is caused by the "ChoiceToValueTransformer" which indeed searches for entries in your pre-declared list. If your list is empty or you want to disable the transformer you can simply reset it.

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('yourField', 'choice', array('required'=>false));

    //more fields...

    $builder->get('yourField')->resetViewTransformers();
}

Then your custom defined validation will step in (if it exists).
