Not working with symfony 2.4

[jimmy6262]

I am trying to make a form with the mandango bundle but it does not work in symfony 2.4.

FatalErrorException: Compile Error: Declaration of
Mandango\MandangoBundle\Form\Type\MandangoDocumentType::buildForm() must
be compatible with
Symfony\Component\Form\FormTypeInterface::buildForm(Symfony\Component\Form\FormBuilderInterface $builder, array $options) in
/path/to/project/vendor/mandango/mandango-bundle/Mandango/MandangoBundle/Form/Type/MandangoDocumentType.php line 104

When i look to the code, it still use
public function buildForm(FormBuilder $builder, array $options)

Can there be a fix for this?
