$this->form->getState() empty

[umbral hedge]

Hi, I've created a Filament page with the make command and I've placed a form inside the component. When I submit my form, $this->form->getState() returns an empty array and I'm not sure why. The $data property however is filled correctly, and my validation also runs fine. Any idea what's wrong with my code? Or shouldn't I use $this->form->getState() and just use $this->data?

My file:

class VolunteerSettings extends Page implements HasForms
{
    use InteractsWithFormActions;
    use InteractsWithForms;

    protected static ?string $navigationIcon = 'heroicon-o-document-text';

    protected static string $view = 'filament.pages.volunteer-settings';

    protected static ?string $slug = 'vrijwilligervoorkeuren';

    protected static ?string $title = 'Vrijwilligervoorkeuren';

    public ?array $data = [];

    public function mount()
    {
        $this->form->fill();
    }

    public function form(Form $form): Form
    {
        return $form
            ->model(auth()->user())
            ->schema([
                Forms\Components\Section::make()
                    ->relationship('volunteerProfile')
                    ->schema([
                        'is_active' => Forms\Components\Toggle::make('is_active')
                            ->label('Actief profiel')
                            ->default(false)
                            ->live(),
                        // ...
                    ]),
            ])
            ->statePath('data');
    }

    public function getFormActions(): array
    {
        return [
            Actions\Action::make('submit')
                ->label('Opslaan')
                ->submit('submit'),
        ];
    }

    public function submit()
    {
        $data = $this->form->getState();
        dd($data, $this->data);
    }
}

you should use saveRelationships()
https://filamentphp.com/docs/3.x/forms/adding-a-form-to-a-livewire-component#passing-the-form-model-after-the-form-has-been-submitted

if you want to get the relationship data using getState(), add ->dehydrated(true) after ->relationship()
