Undefined array key in Repeater Component

[abournavaud]

Hello @AsmitNepali,
When using the plugin inside a Filament Repeater component, I encounter an exception: Undefined array key "<key_name>".

This error occurs when submitting the form, on the dehydrateData function.

Another question: Is it possible to dynamically update other form fields when selecting an element in the component? If so, what's the recommended approach?

Thanks for this great plugin !

@abournavaud Thank you for bringing this issue to my attention. Could you please share a screenshot or any additional details about your implementation? This will help me better understand the problem and provide a more effective solution.

@AsmitNepali I am using the component inside a Repeater as follows:

Forms\Components\Repeater::make('itemRules')
    ->relationship('itemRules')
    ->schema([
        RichMentionEditor::make('description')
            ->mentionsItems(function () {
                return Item::query()->withWhereHas('screen')->get()->map(function ($item) {
                    return [
                        'id' => $item->id,
                        'username' => $item->screen?->name.' - '.$item->name,
                        'name' => $item->item_type?->getLabel().' - '.$item->screen?->name.' - '.$item->name,
                        'avatar' => null,
                        'url' => null,
                    ];
                })->toArray();
            })
            ->lookupKey('username')
            ->required()
            ->maxLength(65535),
    ]),

The component works correctly and displays the expected items in the rich text editor.
However, when saving the form, an error occurs in the dehydrateData() function.

Upon inspecting $state['data'] at that moment, here is its value:

array:1 [▼
  "itemRules" => array:1 [▼
    "record-27" => array:1 [▼
      "description" => "<p>Sequi hic velit tenetur vitae quia voluptatibus iste. Eaque vero ut voluptas dolorum eaque voluptatem. <a href="null(--undefined--)">@sunt - Fernandez</a>&nbsp;</p>"
    ]
  ]
]

Thanks in advance for your help.
