I came across the same problem in 3.5.1
Looks like there's no one assigned to it at 
https://github.com/tonytomov/jqGrid/issues/410 

Is there any work around - like going back to any previous versions (which is 
the last version that isn't affected?) - or looking into the file to fix this 
bug in the grid JS code? Any ideas would be appreciated, thanks!
