Single row updation in editable list view

Hi

I am having a editable list view where 3 columns are there.2 read only and one is editable. It retrieves the data as per id. If for a perticular id,one row is retrieved and if I have to update the one column in single row ,its not updating While if 3 rows are retrieved,then the updation is done properly.

 example: for id =30

code   version  stat

------------------------------

7877      1           

7879      2

7800      3

for id=40

code  version stat

7801      1         

Here for id =30, I am able to update rows as if I add value for stat in one row and if I select  next row,the value gets updated 

but for id=40,if I change value of stat and as there is no other row to click on , if I click outside also value didnt get update.Only after pressing Enter key then the value getting updated.

Please help me in this regard.

Rule  attached.
