the simplest solution is, and naturally replace your variable names; this works for me: 'by_reference' => false

as follows:

protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper
        ->add('name')
        ->add('articles', EntityType::class, array(
            'class' => 'EboxoneAdminBundle:Article',
            'required' => false,
            'by_reference' => false,
            'multiple' => true,
            'expanded' => false,
        ))
        ->add('formInputs', CollectionType::class, array(
            'entry_type' => FormInputType::class,
            'allow_add' => true,
            'allow_delete' => true,
            'by_reference' => false,
        ))
    ;
}
