I have hotel documents that each have rooms of nested type.

```
{
id: hotel_id,
   rooms: [
     {
        id: room_id_1,
        name: "room 1 name"
      },
      {
        id: room_id_2,
        name: "room 2 name"
      },
      ....
  ]
}

```

And I want to update only single field from a specific room. I am trying with the Update api, update the room with id 2 from the hotel document with id 1:

```
POST hotels/_update/1
{
  "script" : {
    "source" : "if(ctx._source.rooms.id == 2) { ctx._source.rooms.name = params.new_name }",
    "lang" : "painless",
    "params" : {
        "new_name" : "new room name"
    }  
  } 
}

```

I get this error "Illegal list shortcut value [id]" from ES.

Thanks!
