Symfony - retreive unmapped fields in nested forms

I'm having a Symfony Type ItemType which is based on an Entity.

class IpQuoteItemsType extends AbstractType
{

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('itemName', TextType::class, [
                'label' => 'Produktname'
            ])
            ...
            ->add('specialDiscount', PercentType::class, [
                'required' => false,
                'label' => 'Sonderrabatt',
                'mapped' => false,
                'attr' => [
                    'placeholder' => 'Sonderrabatt 0,00 %'
                ]
            ])
        ;
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => IpQuoteItems::class
        ));
    }

}

Which is used as a CollectionType in the final form:

class IpQuotesType extends AbstractType
{

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        ...
        $builder->add('products', CollectionType::class, [
            'entry_type' => IpQuoteItemsType::class,
            'data' => $items
        ]);
    }

}

Under no circumstances I receive the unmapped field specialDiscount. It is still available in the PRE_SUBMIT event of the ItemsType but can't be found anywhere in the final form QuotesType.

Is it possible to sumit unmapped data in nested forms?

Also a thank you to @threeside for his solution. I also use a collection field to embed a subform. In my case it is a FileType field to upload images which have to be unmapped for the processing.

With

$subform_data = $form->get('name_of_collection_field')

you get the form data (or is it a symfony form object?) of the subform. In case of a collection field you can iterate over the items with

foreach($subform_data as $subform_item) {
            $items[] = $subform_item->get('unmappedFieldName')->getData();
        }

to collect the items in the $items array. The entire trick is to use the form data/object, from that you can extract unmapped fields.

You can get unmapped field in your controller like this : 

$form->get('nestedEntity')->get('fieldName')->getData()

I don't test with collection but it's work with a customType in OneToOne relation.

Hope this help.
