Changing min/max for Symfony2 range validator at runtime

I need to change the max value for the range validator in Symfony at runtime, while building the form with FormBuilder. Has anybody an idea how to do this?

As I wrote before in my comment I used a solution like this:

first part of the range:

class Entity {
 //@Assert\NotBlank()
 private $property;
}

second part of the range:

$formBuilder->get('property')->addEventListener(FormEvents::POST_SUBMIT,
    function(FormEvent $event) use ($something) {
        $property = $event->getForm()->getData();
        if ($property > $something) {
            $event->getForm()->addError(new FormError(...));
        }
    }
);

Hope this was helpful

Well, Symfony is designed so that the constraints are attached to the underlying object/data, not the form (type) itself.

However, you can add constraints directly to the form if the form is not mapped to a class.

http://symfony.com/doc/current/book/forms.html#adding-validation

Basically, you can define a constraints option in the form builder which should be an array of constraint objects.

use Symfony\Component\Validator\Constraints\Range;

$builder->add('your_field', null, array(
    new Assert\Range(array(
        'min'        => 10
      , 'max'        => $someDyanmicValue
      , 'minMessage' => 'min error message'
      , 'maxMessage' => 'max error message'
    ))
));

If your form is mapped to a class where the Range constraint is defined, you'll have to go about this a different way. Let me know.
