Problem description

When building a dynamic form in Filament (v3.x), we want to show different inputs based on the value of a Select::make('type'). The fields are correctly shown/hidden using visible(), but on the edit page, the existing value is not populated in the input, even though default(fn ($record) => ...) is used.

This makes it impossible to see or edit the previously saved value when editing a record.

Expected behavior

The appropriate input should be visible based on the selected type.

Its value should be populated from the $record->value.

Steps to reproduce

`public static function form(Form $form): Form { return $form->schema([ Select::make('type') ->label('Type') ->required() ->reactive() ->disabledOn('edit') ->default('text') ->options([ 'text' => 'Text', 'number' => 'Number', 'date' => 'Date', 'file' => 'File', ]),

    TextInput::make('value')
        ->label('Text Value')
        ->visible(fn (Get $get) => $get('type') === 'text')
        ->default(fn ($record) => $record?->type === 'text' ? $record->value : null)
        ->dehydrated(fn (Get $get) => $get('type') === 'text'),

    TextInput::make('value')
        ->label('Number Value')
        ->numeric()
        ->visible(fn (Get $get) => $get('type') === 'number')
        ->default(fn ($record) => $record?->type === 'number' ? $record->value : null)
        ->dehydrated(fn (Get $get) => $get('type') === 'number'),

    DatePicker::make('value')
        ->label('Date Value')
        ->visible(fn (Get $get) => $get('type') === 'date')
        ->default(fn ($record) => $record?->type === 'date' ? $record->value : null)
        ->dehydrated(fn (Get $get) => $get('type') === 'date'),
]);

} `

Relevant log output

But if I use only one input (without conditional visibility), then its value is displayed correctly. In other words, if I remove the number, DatePicker, and FileUpload inputs, the value is loaded and shown as expected.

Hi! Default values are only applied on Create and not Edit pages, so as we dont overwrite existing data. See https://filamentphp.com/docs/3.x/forms/fields/getting-started#setting-a-default-value

You could use $set() to set the value of the input in afterStateUpdated() when you choose to show it: https://filamentphp.com/docs/3.x/forms/fields/getting-started#setting-a-default-value, https://filamentphp.com/docs/3.x/forms/advanced#field-updates
