Update Content of Key-Value Field

Hi! I'm new to Filament and need some help with conditional fields: Problem: I have a Select field and a KeyValue field. When the user selects a different option in the select, the data in the kv-field should be updated. But as you can see in this recording, it doesn't really work, only sometimes the field is updated: 🎥 https://krausskomm-my.sharepoint.com/:v:/g/personal/lb_krausskommunikation_de/Ef_yx_bOS9xEqcdP51xW-ugBJmJlNkkxEZv_N0mOp3tnjg?e=pCzNnz&nav=eyJyZWZlcnJhbEluZm8iOnsicmVmZXJyYWxBcHAiOiJTdHJlYW1XZWJBcHAiLCJyZWZlcnJhbFZpZXciOiJTaGFyZURpYWxvZy1MaW5rIiwicmVmZXJyYWxBcHBQbGF0Zm9ybSI6IldlYiIsInJlZmVycmFsTW9kZSI6InZpZXcifX0%3D Fields: - the Select has reactive(), some options() and an afterStateUpdated hook which uses $set('config', []) to update the kv-field - the KeyValue is configured to not allow any modifications (no new rows, no deletions, no key changes) Code:

Forms\Components\Select::make( 'type' )
   ->reactive()
   ->options( [
       'mysql'     => 'MySQL',
       'mysql_ssh' => 'MySQL (SSH)',
       'sftp'      => 'SFTP',
   ] )
   ->afterStateUpdated( function ( Forms\Get $get, Forms\Set $set ) {
       // create a new key-value array depending on the selection...
       $config = match ( $get( 'type' ) ) {
           "mysql" => [
               'hostname' => '',
               // ...
           ],
           "mysql_ssh" => [
               'hostname'     => '',
               // ...
           ],
           "sftp" => [
               'hostname' => '',
               // ...
           ],
           default => [],
       };

       // ...if a key was already filled, keep it...
       foreach ( $get( 'config' ) as $k => $v ) {
           if ( isset( $current[ $k ] ) ) {
               $config[ $k ] = $current[ $k ];
           }
       }

       // ...and finally update the key-value field
       $set( 'config', $config );
   } )
   ->required(),

Forms\Components\KeyValue::make( 'config' )
     ->addable( false )
     ->deletable( false )
     ->editableKeys( false )
     ->columnSpanFull(),

Forms\Components\Select::make( 'type' )
   ->reactive()
   ->options( [
       'mysql'     => 'MySQL',
       'mysql_ssh' => 'MySQL (SSH)',
       'sftp'      => 'SFTP',
   ] )
   ->afterStateUpdated( function ( Forms\Get $get, Forms\Set $set ) {
       // create a new key-value array depending on the selection...
       $config = match ( $get( 'type' ) ) {
           "mysql" => [
               'hostname' => '',
               // ...
           ],
           "mysql_ssh" => [
               'hostname'     => '',
               // ...
           ],
           "sftp" => [
               'hostname' => '',
               // ...
           ],
           default => [],
       };

       // ...if a key was already filled, keep it...
       foreach ( $get( 'config' ) as $k => $v ) {
           if ( isset( $current[ $k ] ) ) {
               $config[ $k ] = $current[ $k ];
           }
       }

       // ...and finally update the key-value field
       $set( 'config', $config );
   } )
   ->required(),

Forms\Components\KeyValue::make( 'config' )
     ->addable( false )
     ->deletable( false )
     ->editableKeys( false )
     ->columnSpanFull(),

I don't see anything related to this on the Key-Value field documentation (https://filamentphp.com/docs/3.x/forms/fields/key-value), same for the Field updates documentation (https://filamentphp.com/docs/3.x/forms/advanced#field-updates). Context: I have a model that has two columns: - type (VARCHAR(100)) - config (TEXT) The config column stores key-value info formatted as JSON, with different keys depending on the type column. Example: | type | config | |--------|-----------------------------------------------| | mysql |{"database":"db1","port":3306} | | sftp |{"hostname":"hello.world","port":22}|
