Symfony3 forms not showing input fields when using CollectionType

Question

I'm having problem with displaying form when using CollectionType. It doesn't show newOrderCustomerType inputs, just label "Customer Id". Whats wrong?

newOrderCustomerType

<?php

namespace AppBundle\Form;

use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class newOrderCustomerType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->
        add('firstname', TextType::class,array('label'=>'Firstname'))->
        add('lastname', TextType::class,array('label'=>'Lastname'))->
        add('email', TextType::class,array('label'=>'Email'))->
        add('login', TextType::class,array('label'=>'Login'));
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'AppBundle\Entity\Customer',
        ));
    }

    public function getName()
    {
        return 'app_bundlenew_order_customer_type';
    }
}

newOrderType

<?php

namespace AppBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class newOrderType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('customerId',CollectionType::class,array(
                'entry_type'=>newOrderCustomerType::class,
                'allow_add'    => true,
                'by_reference' => false,
                'data_class' => 'AppBundle\Entity\Customer',
            ))
            ->add('shopOrderId')
            ->add('orderDate')
            ->add('postBuyFormMsg')
            ->add('invoice')
            ->add('payType')
            ->add('shipmentType')
            ->add('payStatus')
            ->add('save',SubmitType::class);
    }

    public function configureOptions(OptionsResolver $resolver)
    {

    }

    public function getName()
    {
        return 'app_bundlenew_order_type';
    }
}

And in TWIG template

{{ form_start(orderForm) }}
    {{ form_widget(orderForm) }}
{{ form_end(orderForm) }}

How to make it show all input fields?

If you have an active "allow_add" option, it is possible to render this input throught the 'prototype' option:

 $builder
        ->add('customerId',CollectionType::class,array(
            'entry_type'=>newOrderCustomerType::class,
            'allow_add'    => true,
            'by_reference' => false,
            'data_class' => 'AppBundle\Entity\Customer',
            'prototype'     => true,
        ))

and then in the form:

{{ form_row(orderForm.customerId.vars.prototype}) }}

It should work.

For more, see the Symfony documentation of prototype option

Try removing 'data_class', I don't think that's part of CollectionType:

->add('customerId',CollectionType::class,array(
     'entry_type'=>newOrderCustomerType::class,
     'allow_add'    => true,
     'by_reference' => false,
))

See if that works.

Unfortunately it doesn't. I tried adding and removing various options and still nothing...
