Hey @Leandro Ferreira, and thanks a lot for your help! I'm using a repeater, and I want to get values that are outside the repeater I added this rule to one of the repeater attributes, but I it only get the values inside a single repeater

->rules([
    fn (Forms\Get $get): Closure => function (string $attribute, $value, Closure $fail) use ($get) {
        info($get('id'));

->rules([
    fn (Forms\Get $get): Closure => function (string $attribute, $value, Closure $fail) use ($get) {
        info($get('id'));

So that's why I thought of making the validation inside handleRecordCreation and mutateFormDataBeforeSave, but then wondered how to display the validation error before running $this->halt();
