Can't get to work IterableItemCast

[TiiFuchs]

I enabled cast_and_transform_iterables in the config/data.php,

I defined my array like this:

    /** @var array<int, RegionalValidityType> */
    #[WithCast(RegionalValidityTypeCast::class)]
    public array $validRegion;

and in RegionalValidityTypeCast I implemented both interfaces Cast and IterableItemCast.

But no matter what, the complete array will get passed to the "normal" cast method, not per item to the castIterableItem method.

I think I did everything according to the documentation. Is that feature not working correctly or did I miss something?

Ok I digged a little around in the code and learned the following things about Casts and iterables:

• Casts are only meant for casting into an object that does NOT extend the Data class!

• For everything else you could use magic creation methods.

• So my solution was to create a public static function fromArray(array $value): self method inside my abstract base class RegionalValidityType.

• laravel-data seams to call the fromArray method with each item inside your iterable, so you can concentrate on a single item.
