jQuery Grid Plugin - jqGrid

Hi,

I'm using jqGrid 3.5, ASP.NET MVC 1.0 and jQuery UI 1.7.2

The problem I'm having is that this function is failing after adding or editting items:

formatter=

function(rowId,cellval,colpos,rwdat,_act){var cm=ts.p.colModel[colpos],v;if(typeof cm.formatter!=="undefined"){var opts={rowId:rowId,colModel:cm};if($.isFunction(cm.formatter)){v=cm.formatter(cellval,opts,rwdat,_act)}else{if($.fmatter){v=$.fn.fmatter(cm.formatter,cellval,opts,rwdat,_act)}else{v=cellVal(cellval)}}}else{v=cellVal(cellval)}return

v},

On firebug and visual studio's debugger I can see that colpos = 4 which for my colModel is wrong because there's only 4 fields in it (colpos should be at most 3).

A strange thing is that if I add, get the error, and then refresh the page the grid displays all changes correctly.

I can provide the code I'm using and some sample json data.

Thanks in advance
