title: Repository spinEdit issue
body: <p>I have read many articles here about spin edit and just cant solve this problem... I added spin Edit and check Edit repositories in my tree list columns, but when i press spin Edit up/down arrows, value is not changing. And when i click on check Box, it's value is not changing (checked/unchecked). Instead, when i expand node and double Click spin Edit arrows or edit Check Box, node collapses :) tried many things, but cant change value of these repositories...</p>
  
  <p>I found same question here, but noone answerred it:
