Bug Report

Q	A
Version	3.5.0

Summary

Deleting an entity with hooked identifier property on PHP 8.4 throws an error "Cannot unset hooked property EntityClass::$id"

Current behavior

After deleting entity from database Doctrine trying to unset identifier property on entity object, but if identifier property has hook PHP throws an error, because unsetting property with hook does not supported

Expected behavior

Doctrine delete an entity with hooked identifier property successfully

How to reproduce

Create an entity with hooked identifier property

<?php

use Doctrine\ORM\Mapping as ORM;
use Symfony\Bridge\Doctrine\IdGenerator\UuidGenerator;
use Symfony\Component\Uid\Uuid;

#[ORM\Entity]
#[ORM\Table('entity')]
class Entity
{
    #[ORM\Id]
    #[ORM\GeneratedValue(strategy: 'CUSTOM')]
    #[ORM\CustomIdGenerator(UuidGenerator::class)]
    #[ORM\Column(type: 'uuid', nullable: false)]
    public Uuid $id {
        get => $this->id;
        set => $this->id = $value;
    }
}

Create and delete entity

<?php

$entity = new Entity();

$em->persist($entity);
$em->flush();

$em->remove($entity);
$em->flush(); // An exception is thrown here

Can confirm the same issue is present when hydrating lazy collections with hooked properties whose values are null. The property accessor is trying to unset them, which it no longer can do with hooked properties:

Same problem here, a quick fix is to make your hook property nullable:

public MyType $data { set => $this->data = someAationOnValue($value)); }
Become
public ?MyType $data { set => $this->data = someAationOnValue($value)); }
