Not possible to give AssociationField an alternative getter?

[ciaranmcnulty]

Describe the bug

I have an entity with a 'broken' getter, which for legacy reasons I can't safely change the signature of.

1. I've not been able to see a way to get AssociationField to use an alternative getter for this field
2. The error message is not clear, so some error checking may be missing

Example entity:

#[Entity]
#[Table(name: 'users')]
final readonly class User
{
    #[Id]
    #[Column(type: Types::INTEGER)]
    #[GeneratedValue]
    public int $id;

    #[Column(length: 100)]
    public string $name;

    #[ManyToOne]
    private ?User $parent;

    /** Existing accessor relied on by legacy system */
    public function getParent() : User|false
    {
        return $this->parent ?? false;
    }

    /** Accessor added to allow EasyAdminBundle to access the real data */
    public function getAdminParent() : ?User
    {
        return $this->parent;
    }
}

I try to set the form to use the alternative getter:

        yield AssociationField::new('parent')
            ->setFormTypeOption('getter', 'getAdminParent');

But as soon as I navigate to the /new page I get an exception:

TypeError:
Cannot use "::class" on false

To Reproduce Repository here

Boot up and navigate to /admin/user/new

I think you can do this : yield AssociationField::new('adminParent'); but you also need to create a setter

Or Maybe

yield AssociationField::new('adminParent')
    ->setProperty('parent');

[ciaranmcnulty]

@dwd-akira Unfortunately your suggestion doesn't work, it still leads to an attempt to read the parent field via propertyaccess, which then uses the getParent method without out any way I can see to override it

(your suggested syntax would make sense!)

[dwd-akira]

And if you create a fake property

#[ManyToOne]
    private ?User $parent;

private ?User $adminParent;

yield AssociationField::new('adminParent')
    ->setProperty('adminParent');
