Extending ListPage doesn't work in v3
Upon upgrading to v3, I found out that the columns in the custom page show the same columns as in the ListPage, although I have the following:
use Filament\Tables\Columns\TextColumn;
...
class InvoiceStats extends ListInvoices
{
protected static string $resource = InvoiceResource::class;
protected static string $view = 'filament.resources.invoice-resource.pages.invoice-stats';
protected function getTableColumns(): array
{
return [
TextColumn::make('invoice_number')
->label('Invoice #')
->searchable(),
...
];
}
