Hello,
I do not thisnk tha the problem is in the grid, but rather in the code and what you ask in the ajax request.
The form editing is not changed from 4.3.3 to 4.4.0 you can check this.
Regards
Hi, tnx for the reply…
As I said before the same code works perfectly with 4.3.3, and you too wrote that the form editing is not changed: so the error is surely with 4.4.0 
btw I'll check, but if the jqgrid documentation is the same i don't know how to change my code to try…
