"Property type not supported in Livewire for property" when using custom casts

I have a json field on my model, where I use a custom class as a cast:

    protected $casts = [
        "hotel_texts" => HotelText::class,
    ];

    protected $casts = [
        "hotel_texts" => HotelText::class,
    ];

This fields contains only 3 properties and I am displaying the form like this:

TextInput::make("hotel_texts.field1"),
TextInput::make("hotel_texts.field2"),
TextInput::make("hotel_texts.field3"),

TextInput::make("hotel_texts.field1"),
TextInput::make("hotel_texts.field2"),
TextInput::make("hotel_texts.field3"),

This worked in v2 without any problems, now in v3 I get an error:

Property type not supported in Livewire for property: [{"field1":"..

Property type not supported in Livewire for property: [{"field1":"..

The HotelText implements the implements CastsAttributes, ArrayAccess interfaces. When changing the cast to array, it works as well. Any ideas to get around this?

Encountered the same problem today with code I ported from v2, seems to be a livewire issue For now I just removed my custom casts

Try making your custom cast class Wireable: https://livewire.laravel.com/docs/properties#wireables

You'll need to read the whole Properties page to understand what's happening and why LW doesn't understand your type, and you could consider using a Synthesizer, although that's probably overkill: https://livewire.laravel.com/docs/synthesizers

TL/DR, Livewire 3 needs to know how to convert any property to and from JSON. It has built in support for all the common datatypes, but if you need to wire.model a custom class, you need to make it Wireable, with toLivewire and fromLivewire methods, so LW knows what to do with it.

Thanks. I implemented Wireable and now the form is showing, but on save I get

This synth doesn't support setting properties: Livewire\Features\SupportWireables\WireableSynth

This synth doesn't support setting properties: Livewire\Features\SupportWireables\WireableSynth

Its not an option for me, for now, since I have implmented some methods I use on the cast classes

You may need a synthesizer. I would have thought simply making it wireable would work, but I'm still a little hazy on the difference. Synthesizers aren't hard, though, and are well documented.
