Tony I don't have differences in fields. In filterGrid I want to use the same colModel. I don't think that the problem is in my code because it's quite simple. If I delete “edittype:”select”” from the second column (type_worker) everything works well, but with “edittype:”select”” add/edit forms don't work. Also add/edit forms work if I delete the line with filterGrid (the last line in my code)

jQuery(document).ready(function(){
var lastsel;
