Hi, i'm having an issue with jqgrid groupingGroupBy with chrome only, the grid freeze with “loading” modal over and in chrome i see this error on console:

Uncaught TypeError: Cannot read property 'name' of undefined

and point to this line in the code:

$('#noSData').jqGrid('groupingGroupBy',['PField'], { groupColumnShow: [false], groupDataSorted: true, groupCollapse: true} );
