I was facing the same issue. After debugging the issue I figured out that its a Bug in JQGrid (i am using latest 4.3.1). Whenever you define a table in any column (using column formatter) and try to retrieve the value of that column later (given that you have also defined your unformatter functions properly) you will face this issue.

Its fix is as follows:

Open the source file jquery.jqGrid.src.js and replace the following line

$('td',ind).each( function(i) {

with this line

$('td[role=”gridcell”]',ind).each( function(i) {

and you are Done ! 🙂
