I am using v4.2.0 and have discovered an issue with the column custom formatter function.  It appears that it can be called with two different parameter types for the rowObject param under different circumstances.  Here is the documentation link for the function: http://www.trirand.com/jqgridw....._formatter

The function is defined to conform to the following:

function myformatter ( cellvalue, options, rowObject )
{
// format the cellvalue to new format
return new_formated_cellvalue;
}

rowObject is supposed to be the data for the row, and when initally called always is. However, I am making the cell editable using using the select type in the colmodel definition like this:

                   { 	name: 'state',  
                    	index: 'state', 
                    	editable: true,  
                    	edittype: 'select',  
                        editoptions : 
                        {
                        	value : getSelectString()
                        },
                        formatter: 	function ( cellvalue, options, rowObject )
            			{
					return "new value";
            			},
                    }, 

The problem happens if I do the following:

1. Start to edit the cell which creates a select object in the cell.
2. Hit "esc" to cancel the edit, making the select disappear.
3. At this point the formatter is called with a HTMLTableRowElement  rather than a standard rowObject with the col values in it.  

The offending caller is in the "setCell" method at line 3117 in the jquery.jqGrid.src.js.  Specifically, these lines seem to be at fault:

var ind = $t.rows.namedItem(rowid);
if (ind){
var tcell = $("td:eq("+pos+")",ind);
if(nData !== "" || forceupd === true) {
v = $t.formatter(rowid, nData, pos,ind,'edit');
