Embedding nested form type fields in empty symfony form

I have form type for a Shop entity. This links in a 1-1 relationship to a ShopAddress entity.

When I nest the ShopAddress entity it appears blank when creating a new shop. How can I get this to render with the relevant blank fields when creating a new Shop?

// App/Froms/ShopType.php
class ShopType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add( "name" ) // rendering fine
            ->add( "shopAddress", CollectionType::class, [
                "entry_type" => ShopAddressType::class, // no visible fields
            ] )
        ;
    }


    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            "data_class" => Shop::class,
        ));
    }
}

// App/Froms/ShopAddressType.php
class ShopAddressType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add("addressLine1", TextType::class ) // not rendering
            ->add("addressLine2") // not rendering
            ->add("postcode") // not rendering
            ->add("county"); // not rendering
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            "data_class" => ShopAddress::class,
        ));
    }
}

Yep. Solved it. Docs had the answer You need to add it as a new FormBuilderInterface object in the add() method: 

class ShopType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add("name", TextType::class)
            ->add(
                // nested form here
                $builder->create(
                    'shopAddress', 
                    ShopAddressType::class, 
                    array('by_reference' => true ) // adds ORM capabilities
                )
            )
        ;
    }


    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            "data_class" => Shop::class,
        ));
    }
}

Adding array('by_reference' => true ) will allow you to use the full ORM (Doctrine in my case) capabilities (e.g. $shop->getAddress()->setAddressLine1('this string to add')).
