[LiveComponent] Live properties in onUpdated hook are null... bug or normal behaviour?

[gremo]

In my QuantityControl component I need to adjust the value live property based on min and max live properties:

<twig:QuantityControl max="3" />

I have this following problem:

• Calling adjustValue from a live action works, I can access max value
• When adjustValue is called by the framework using the onUpdated hook... max is null

<?php

namespace App\Twig\Components;

use Symfony\UX\LiveComponent\Attribute\AsLiveComponent;
use Symfony\UX\LiveComponent\Attribute\LiveAction;
use Symfony\UX\LiveComponent\Attribute\LiveProp;
use Symfony\UX\LiveComponent\ComponentToolsTrait;
use Symfony\UX\LiveComponent\DefaultActionTrait;
use Symfony\UX\TwigComponent\Attribute\ExposeInTemplate;

#[AsLiveComponent]
class QuantityControl
{
    use DefaultActionTrait;

    #[LiveProp]
    public int $min = 0;

    #[LiveProp()]
    public ?int $max = null;

    #[LiveProp]
    public int $step = 1;

    #[LiveProp(writable: true, onUpdated: 'adjustValue')]
    public ?int $value = 0;

    #[LiveAction]
    public function up()
    {
        $this->value += $this->step;
        // $this->adjustValue(); // When called from up(), max property is not null
    }

    #[LiveAction]
    public function down()
    {
        $this->value -= $this->step;
        // $this->adjustValue(); // When called from down(), max property is not null
    }

    public function adjustValue(): void
    {
        // Here max property is null, despite being passed
        dd($this->max);
    }
}

The component twig if matters:

<div {{ attributes }}>
    <button data-action="live#action" data-live-action-param="up">
        +
    </button>
    <input data-model="value">
    <button data-action="live#action" data-live-action-param="down">
        -
    </button>
</div>

This is something @weaverryan started to work. Originnaly the actions were not designed to be called from PHP, but this is somethings that has been asked several time, so he started to digg in this question.

Currently (and probably until 2.18) you're right: those hooks are only called once, during dehydration.

Stay tuned :)

Ok then, I'm going to close this as It seems a known issue or a missing feature!
