Inject Set into Action - not possible in V4?

How can we help you?

Regarding to the v3 docs, it was possible to inject Set $set in to an Action like so:
https://filamentphp.com/docs/3.x/forms/actions#form-component-action-utility-injection

When I do the same in v4 (using $schemaSet instead of $set according to https://filamentphp.com/docs/4.x/actions/overview), I get this error:
"Call to a member function makeSetUtility() on null"

My Action lives right in the middle of a form of a custom page:

public function form(Schema $schema): Schema
{
    return $schema->schema([
            Select::make('select1'),
            Select::make('select2'),
            Action::make('test')
                ->action(function (Set $schemaSet, $data) {
                    // set the state of the KeyValueEntry field below based on the two select fields above
                }),
            KeyValueEntry::make('response'),
        ])
        ->statePath('data');
}

When I remove the Set $schemaSet parameter from the action() call, the error message goes away.

Is there another way to access the form's component and set its state without using the $schemaSet parameter? Or is this a bug and it should work? Then I will happily file a regular bug report.

As an additional problem, dd($data) within the action function always returns an empty array. I suppose I should be able to get the current form data via $schemaGet, but this also does not work.

To give you a bigger picture of what I am trying to achieve here:

Using the two select boxes, the user selects what API to query. I want the button to actually do the API request and display the result of the request in the KeyValueEntry below.

If there is a simpler method of doing this, I will happily restructure everything ;-)

I'm rewriting an app that was previously built in ZF1 with jQuery. (Yeah, the good old days...) The form simply postet to the same URL, and if there was a post request, the application called the API and rendered the result below the form. Now I'm trying my best to do the same thing in Filament - and I've been struggeling for days now. Everything around resources and their tables and forms is so easy and great in Filament, I could sing songs of praise all day. But when it comes to custom pages, it makes me want to pull my hair out ;-)

You mean something like this?

public function form(Schema $schema): Schema
{
    return $schema->schema([
        Select::make('select1')
            ->live()
            ->default('option2')
            ->options([
                'option1' => 'Option 1',
                'option2' => 'Option 2',
                'option3' => 'Option 3',
            ]),
        Select::make('select2')
            ->live()
            ->options([
                'optionA' => 'Option A',
                'optionB' => 'Option B',
                'optionC' => 'Option C',
            ]),
        KeyValueEntry::make('response')
            ->state(fn (Get $get) => [
                'select1' => $get('select1'),
                'select2' => $get('select2'),
            ]),
    ])
        ->statePath('data');
}

if you are using a form in a custom livewire component, don't forget to do this

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

[Estigy]

Yeah, something like this - only that filling the KeyValueEntry with data shall happen after a button click as there is a quite expensive API call involved for getting the data.

(The mount() function is correctly included in my page; everything else is working as expected.)

use Filament\Schemas\Components\Actions

try this

use Filament\Actions\Action;
use Filament\Forms\Components\Select;
use Filament\Infolists\Components\KeyValueEntry;
use Filament\Schemas\Components\Actions;
use Filament\Schemas\Components\Utilities\Get;
use Filament\Schemas\Components\Utilities\Set;
use Filament\Schemas\Schema;

public function form(Schema $schema): Schema
{
    return $schema->schema([
        Select::make('select1')
            ->default('option2')
            ->options([
                'option1' => 'Option 1',
                'option2' => 'Option 2',
                'option3' => 'Option 3',
            ]),
        Select::make('select2')
            ->options([
                'optionA' => 'Option A',
                'optionB' => 'Option B',
                'optionC' => 'Option C',
            ]),

        Actions::make([
            Action::make('submit')
                ->action(function (Get $get, Set $set) {
                    $set('response', [
                        'selected1' => $get('select1'),
                        'selected2' => $get('select2'),
                    ]);
                }),
        ]),
        KeyValueEntry::make('response')
            ->state(null),
    ])
        ->statePath('data');
}

Wow, this was fast!
Thanks for all the details, will try that :-)
