fnUpdate for a single cell with objects

i would like to update a cell with an object. but i am getting error while doing so by fnUpdate . Inside fnRowCallback function i will convert this object to a string and i will put this string in the column. please help me in this.

The following line is causing the issue.
var mapConfig = {};
mapConfig["key1"] = "value1";
oTable.fnUpdate(mapConfig,index-1,4);

The error that i am getting is "DataTables warning (table id = 'resultsTable'): Requested unknown parameter '0' from the data source for row 0".

if i pass a string in fnUpdate it accepts it.for example the following is working.
oTable.fnUpdate(JSON.stringify(mapConfig),index-1,4);

initially when i loaded the table i passed a map to aData[4] via ajax response. and inside the fnRowCallback i converted it to a string as given below.

var string = '';
var mapConfig = aData[4];
for(var key in mapConfig ) {
string += key;
string += '=';
string += mapConfig [key];
}
$('td:eq(4)', nRow).html(string);
Everything was fine till this point. i stored the object in dataTable. only while loading the table i converted the object(map) to a string inside fnRowCallback for displaying purpose.

My question is the dataTable was accepting a map object while loading it via sAjaxSource. but later when i try to update the stored map object using fnUpdate it is not working. How can i change the stored object. is there any workaround for this?

thanks in advance.

DataTables 1.9.4 should be able to handle the situation you describe. Which version are you using? Can you please link to a live test case so I can debug and fix it?
