fix: Child components receive null state when using array data with Infolist state()

[Luca-Lin]

Problem

When using ActivitySection with array data passed via Infolist::state(), child components (ActivityTitle, ActivityDescription, ActivityDate, ActivityIcon) receive null from their $getState() method instead of the actual data.

Environment:

• PHP 8.3
• Filament 3.x (latest)
• Laravel 10.x / 11.x

Example usage that fails:

public function activityInfolist(Infolist $infolist): Infolist
{
    return $infolist
        ->state([
            'activities' => [
                [
                    'title' => 'John Doe',
                    'description' => 'Created a new record',
                    'status' => 'create',
                    'created_at' => now(),
                ],
            ],
        ])
        ->schema([
            ActivitySection::make('activities')
                ->schema([
                    ActivityTitle::make('title'),
                    ActivityDescription::make('description'),
                    ActivityDate::make('created_at'),
                    ActivityIcon::make('status'),
                ]),
        ]);
}

Expected behavior: Child components display the data (title, description, etc.)
Actual behavior: Child components display placeholder text because $getState() returns null

Root Cause

In ActivitySection::getChildComponentContainers(), the method sets statePath($itemKey) for each child container, but when $itemData is an array (not a Model), the state data is not properly passed to child components:

foreach ($this->getState() ?? [] as $itemKey => $itemData) {
    $container = $this
        ->getChildComponentContainer()
        ->getClone()
        ->statePath($itemKey)
        ->inlineLabel(false);

    if ($itemData instanceof Model) {
        $container->record($itemData);  // Only Models get their data set
    }
    // Arrays are ignored - child components can't access the data!

    $containers[$itemKey] = $container;
}

Solution

Pass the array data to child containers using state() method when the data is not a Model:

foreach ($this->getState() ?? [] as $itemKey => $itemData) {
    $container = $this
        ->getChildComponentContainer()
        ->getClone()
        ->statePath($itemKey)
        ->inlineLabel(false);

    if ($itemData instanceof Model) {
        $container->record($itemData);
    } elseif (is_array($itemData)) {
        $container->state($itemData);
    }

    $containers[$itemKey] = $container;
}

Changes

• Modified src/Components/ActivitySection.php to handle array data in getChildComponentContainers() method
