Collection field validation errors not placed correctly

[skyferix]

Collection fields validation error are not being rendered in proper location. Could there be the case that error fields are not being rendered for the custom form fields at all? If yes what could code look like? Do i need to define whole form template or field template for single error is enough?

Using easy admin 4.5.1. Basically using custom form type to render colletion field and errors are not beeign mapped correctly. Tried set error_bubbling to false and using error_mapping bouth to parent field 'agents' and sub-form field 'name' but it did not help.

Took a second look at the problem. The issue lies in collection starting at index 1 and assert asserting at index 0. Still searching to solutions how to make them match

After investigation find the same problem over here -> https://github.com/symfony/symfony/issues/7468#issuecomment-213411710

And after modifing the code end up with this code in my crud controller: Hope it helps someone because it was big pain for me. I don't know how this bundle handles Field related logic but it whould be nice to add Colletion field access to form in order to add listener. Then creating custom Field with listener defined in it could be really nice.

`public function createNewFormBuilder( EntityDto $entityDto, KeyValueStore $formOptions, AdminContext $context ): FormBuilderInterface { $formBuilder = parent::createNewFormBuilder($entityDto, $formOptions, $context);

    return $this->buildForm($formBuilder);
}

public function createEditFormBuilder(
    EntityDto $entityDto,
    KeyValueStore $formOptions,
    AdminContext $context
): FormBuilderInterface {
    $formBuilder = parent::createEditFormBuilder($entityDto, $formOptions, $context);

    return $this->buildForm($formBuilder);
}

public function buildForm(FormBuilderInterface $builder): FormBuilderInterface
{
    return $builder->addEventListener(FormEvents::PRE_SUBMIT, array($this, 'onPreSubmit'));
}

public function onPreSubmit(FormEvent $event)
{
    $data = $event->getData();
    $object = $event->getForm()->getData();

    // Loop on form fields
    foreach ($event->getForm()->all() as $field) {
        $fieldName = $field->getName();
        if ($field->getConfig()->getType()->getInnerType() instanceof CollectionType) {
            if (isset($data[$fieldName]) && $object) {
                $collection = $data[$fieldName];
                $data[$fieldName] = [];
                $k = -1;
                foreach ($object->{'get' . ucfirst($fieldName)}() as $k => $item) {
                    // Search
                    foreach ($collection as $i => $c) {
                        $cId = is_array($c) && isset($c['id']) ? $c['id'] : $c;
                        if ($item->getId() == $cId) {
                            $data[$fieldName][$k] = $c;
                            unset($collection[$i]);
                            break;
                        }
                    }
                }
                // Added items
                foreach ($collection as $c) {
                    $data[$fieldName][++$k] = $c;
                }
            }
        }
    }

    $event->setData($data);
}`

same problem for me, errors are not set to the right place when using _errormapping and _errorbubbling = false
