[Bug]: The component class constructor doesn't seem to run when using ComponentColumn

[nathan-io]

What happened?

We're trying to use a Blade component as a column:

            ComponentColumn::make('Fine Content', 'fine_weight_ozt')
                ->component('weight-with-conversions')
                ->attributes(fn ($value, $row, Column $column) => [
                    'weight' => new Weight($row->weighing_unit_type, $row->fine_weight),
                ]),

This does cause livewire-tables to attempt to render the component view, but it throws an "Undefined variable" exception because the public properties that are set in the constructor aren't present.

I don't believe the problem is in the component, because it works without issue when called in a view:

@php
     $weight = new App\Data\Weight(1, 1)
@endphp
<x-weight-with-conversions :weight="$weight" />

So perhaps the constructor is not firing?

---

Here's the component class and view:

...
class WeightWithConversions extends Component
{
    public Weight $weight;
    public string $conversions;

    /**
     * Create a new component instance.
     */
    public function __construct(Weight $weight)
    {
        $this->weight = $weight;

        $this->conversions =
            $weight->toString(WeighingUnitType::TroyOunce) . '<br/>' .
            $weight->toString(WeighingUnitType::Gram) . '<br>' .
            $weight->toString(WeighingUnitType::Pennyweight);
    }

    /**
     * Get the view / contents that represent the component.
     */
    public function render(): View|Closure|string
    {
        return view('components.weight-with-conversions');
    }
}

View:

<button data-popover data-tippy-content="{!! $conversions !!}" class="underline-dotted">
    {{ $weight->toString() }}
</button>

Thanks for raising, I'll have a look in a bit, just so I can confirm:

class WeightWithConversions extends Component

Is that: Livewire\Component or Illuminate\View\Component

I'm assuming the latter?

[nathan-io]

It's a Blade component.

<?php

namespace App\View\Components;

use Closure;
use Illuminate\Contracts\View\View;
use Illuminate\View\Component;
use App\Data\Weight;
use App\Enums\Item\WeighingUnitType;

class WeightWithConversions extends Component
{
    public Weight $weight;
    public string $conversions;

    /**
     * Create a new component instance.
     */
    public function __construct(Weight $weight)
    {
        $this->weight = $weight;

        $this->conversions =
            $weight->toString(WeighingUnitType::TroyOunce) . '<br/>' .
            $weight->toString(WeighingUnitType::Gram) . '<br>' .
            $weight->toString(WeighingUnitType::Pennyweight);
    }

    /**
     * Get the view / contents that represent the component.
     */
    public function render(): View|Closure|string
    {
        return view('components.weight-with-conversions');
    }
}

Perfect, thanks, I'll take a look shortly.

Just having a look at why this isn't working for you, as I have a ComponentColumn working in my test environment. Will see if I can figure out why it works for me and not for you!

[nathan-io]

Thanks for looking into this!

I see one potential issue (weighing_unit_type has a cast), I'll investigate and update this.

[nathan-io]

I looked at it, still no luck. The Weight constructor throws an exception if supplied invalid arguments.

I put a dd() in the component constructor, but I don't get a dump when I view the page with the table. I move the dd() to the component view, and I do.

Can you show me your working test?

[lrljoe]

I'll have to share it tomorrow, as I'm tuckered out now: See Here for why! That should all get merged in, possibly tomorrow as a new release. But then I will definitely share my working example!

Although glancing at it, I think mine may be an anonymous component, which would explain a lot as to why mine is working and yours isn't.

I'll pop the code open tomorrow to see if I can figure out what's going on there.

Yes I think this is the difference.
