[LiveComponent] `onUpdated` hook is not called on `formValues`

[norkunas]

I am using ComponentWithFormTrait and need to save submitted values (draft mode until full form submit).
So I though that overriding $formValues and adding a hook will work. But that's not the case 🤔

class Component {
    // ...

    #[LiveProp(writable: true, fieldName: 'getFormName()', onUpdated: 'formValuesUpdated')]
    public array $formValues = [];

    public function formValuesUpdated(): void
    {
        // never called
    }
}

Is there a better way to hook for this?

PostHydrate ?

Thanks. it's a minus that I can't inject Request and need to interact with RequestStack..
But why onUpdated hook does not work here?

I believe props were not made for complex objects at first (as we should repeat these values are serialized and accessible entirely in the DOM
