Serializer: type casting for denormalization to public properties

[SpiGAndromeda]

Description
The Symfony serializer supports type casting at denormalization if getters, setters and issers are used in the target class. Unfortunatly, it doesn't support that casting (of primitive types) with public typed properties. The PropertyInfo component should be able to deliver the necessary information.

Example
I hit this problem when trying to deserialize a request query into a DTO with public properties.

<?php

declare(strict_types=1);

use Symfony\Component\Validator\Constraints as Assert;

final class SearchRequest
{

    #[Assert\NotBlank(allowNull: true)]
    public ?string $addressCity = null;

    /**
     * @Assert\NotBlank(allowNull = true)
     * @Assert\AtLeastOneOf({@Assert\IsNull, @Assert\Regex(ZipCode::ZIP_CODE_PATTERN)})
     * TODO: replace this annotations with PHP8 attributes as soon as nesting is possible.
     *
     * @see https://github.com/symfony/symfony/issues/38503
     */
    public ?string $addressZipCode = null;
    #[Assert\NotBlank(allowNull: true)]
    public ?string $name = null;
    #[Assert\GreaterThanOrEqual(1)]
    public int $page = 1;
    public bool $pagination = true;
    #[Assert\Choice(choices: Type::ALLOWED_TYPES)]
    public ?int $type = null;
}

The non-string attributes are skipped in the deserialization process with only using denormalize. Complete deserialization for query strings, would be nice too. But that's a different story.

I can't reproduce your issue. The non-string attributes are still deserialized.

Here is my code:

<?php

require_once 'vendor/autoload.php';

use Symfony\Component\Serializer\Encoder\JsonEncoder;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
use Symfony\Component\Serializer\Serializer;

class SearchRequest
{
    public ?string $addressCity = null;
    public ?string $addressZipCode = null;
    public ?string $name = null;
    public int $page = 1;
    public bool $pagination = true;
    public ?int $type = null;
}

$serializer = new Serializer([new ObjectNormalizer()], [new JsonEncoder()]);
$request = $serializer->deserialize(file_get_contents(__DIR__.'/request.json'), SearchRequest::class, 'json');
var_dump($request);

and the JSON file:

{
    "addressCity": "city",
    "addressZipCode": "zip",
    "name": "name",
    "page": 2,
    "pagination": false,
    "type": 0
}

and finally here is my output:

class SearchRequest#16 (6) {
  public ?string $addressCity =>
  string(4) "city"
  public ?string $addressZipCode =>
  string(3) "zip"
  public ?string $name =>
  string(4) "name"
  public int $page =>
  int(2)
  public bool $pagination =>
  bool(false)
  public ?int $type =>
  int(0)
}

Can you provide a minimal reproducer, please?
