Problem description

When a Builder is used in a Resource managed by filament/spatie-laravel-translatable-plugin, the error Undefined array key "afterItem" is returned when trying to insert a block between others.

I was able to trace the error to this line and it arises because the blocks for translations do not have a UUID:

filament/packages/forms/src/Components/Builder.php

Line 190 in 27dca4d

if ($uuid === $arguments['afterItem']) {

Here is the dump for the $arguments when saving in English:

Here is the dump for the $arguments when saving in other languages.
We can see the UUID and afterItem key is missing.

Here is the full error in video:

Expected behavior

No error should occur.

Steps to reproduce

• Clone the repository.
• Migrate
• Seed
• Go to Products, edit any.
• Switch to FRENCH
• Try inserting a block between the two existing.

@AlexisSerneels Hi! There are two reasons why this happens: When you switch the locale to French in your example, the spatie-laravel-translatable-plugin resets the data array keys from uuid's to integers (plugin code). Then, in our block-picker.blade.php, we have an if statement where we check that the $afterItem variable is set, but because it has a zero value, it fails. See the video below, please:

As a quick solution you can create a new class that extends Filament\Forms\Components\Builder\Block and create custom view for it with "isset" fix.
