Can not implement a Filament Repeater as attribute field

[tdwesten]

• Lunar version: v1.0.0-beta.4
• Laravel Version: v11
• PHP Version: 8.3.15
• Database Driver & Version: Mysql

Expected Behaviour:

I can use the Filament Repeater field to create more complex data structures based on a array of objects.

Actual Behaviour:

When I create a custom attribute field using the Filament Repeater field, which extends from the Lunar List field, it doesn't render existing data and throws this error:

Filament\Forms\ComponentContainer::getRawState(): Return value must be of type Illuminate\Contracts\Support\Arrayable|array, stdClass returned

Steps To Reproduce:

1. Create a new field:

<?php

namespace App\Domain\Lunar\Fields;

use Lunar\FieldTypes\ListField;

class ProductDimensionsField extends ListField {}

2. Create a field type:

<?php

namespace App\Domain\Lunar\FieldTypes;

use App\Domain\Lunar\Synthesizers\ProductDimensionsFieldSynth;
use Filament\Forms\Components\Component;
use Filament\Forms\Components\Repeater;
use Filament\Forms\Components\TextInput;
use Lunar\Admin\Support\FieldTypes\ListField;
use Lunar\Models\Attribute;

class ProductDimensionsFieldType extends ListField
{
    /**
     * Specify the Synthesizer for this field type
     */
    protected static string $synthesizer = ProductDimensionsFieldSynth::class;

    /**
     * Define the Filament component for rendering
     */
    public static function getFilamentComponent(Attribute $attribute): Component
    {
        return Repeater::make($attribute->handle)
            ->collapsed()
            ->itemLabel(fn (array $state): ?string => self::getLabel($state))
            ->columns(3)
            ->schema([
                TextInput::make('length')
                    ->numeric()
                    ->label('Length')
                    ->required(),
                TextInput::make('depth')
                    ->numeric()
                    ->label('Depth')
                    ->required(),
                TextInput::make('height')
                    ->numeric()
                    ->label('Height')
                    ->required(),
                TextInput::make('label')
                    ->label('Label')
                    ->required(),
            ])
            ->addable()
            ->deletable()
            ->reorderable();
    }

    /**
     * Get the label for the repeater item
     */
    protected static function getLabel(array $state): ?string
    {
        return sprintf(
            '%s | Price: %s - Updated: %s',
            $state['label'],
            $state['price_formatted'] ?? 'N/A',
            $state['elfsquad_update_timestamp'] ?? 'N/A'
        );
    }
}

3. Create a Livewire Synthesizer

<?php

namespace App\Domain\Lunar\Synthesizers;

use App\Domain\Lunar\Fields\ProductDimensionsField;
use Lunar\Admin\Support\Synthesizers\ListSynth;

class ProductDimensionsFieldSynth extends ListSynth
{
    /**
     * Unique key for the synthesizer
     */
    public static $key = 'lunar_dimensions_field';

    protected static $targetClass = ProductDimensionsField::class;
}

And register it field in your service provider.

        AttributeData::registerFieldType(ProductDimensionsField::class, ProductDimensionsFieldType::class);
