getItemById including select statement possible?

Hi, I sometimes have seen code that uses getItemById with additional parameters. It seems that it´s also possible to include a select statement. Is it actually possible to do something like this? var myManufacturer = inn.getItemById("Manufacturer", myid ,0,null,"name,city"); I currently assume the following syntax: getItemById(ItemType, id, levels, something related to levels, select properties); I wasn´t able to use this one successfuly yet, as the additonal parameters were ignored in my testa. So the method will return the complete Item. Does anybody know if this one can work at all? Best regards! Angela
