mRender gives warning: DataTables warning (table id = 'someTypeTable'): Requested unknown parameter

Hello,

I am looking for some help to avoid the warning -
DataTables warning (table id = 'someTypeTable'): Requested unknown parameter '0' from the data source for row 0 - when am rendering the column(s) using the mRender option.

Versions used as below:
DataTables v1.9.4
jQuery v1.7.1
jQueryUI v1.8.11


Scenarios as below:
Scenario 1:
When am trying to render couple of columns using mRender in order to show a radio button (in one column) and a concatenated information in another column, as below, am getting the warning:

DataTables warning (table id = 'someTypeTable'): Requested unknown parameter '0' from the data source for row 0

someTypeDataTable = $("#someTypeTable").dataTable({
	iDisplayLength: 25,
	aaData: jsonData["someTypes"],
	aoColumns:[
                {"mRender":function(data, type, row){
			//console.log(data, ' - ', type, ' - ', row);
			var radioBtn = "<input type='radio' name='someTypeId' value='";
			radioBtn += row.someTypeId;
			radioBtn += "'/>";
			return radioBtn;
		}},
	        {"mData":"someTitle"},
		{"mRender":function(data, type, full){
			var dimension = full.dimensions + "&#09;" + full.uom;
			return dimension;
		}},
		{"mData": "notes"}
	],
	bProcessing: true,
	bRetrieve: true
});

Scenario 2:
If I am rendering the datatable with a well-formed json data using mData, it is working fine.

someTypeDataTable = $("#someTypeTable").dataTable({
	iDisplayLength: 25,
	aaData: jsonData["someTypes"],
	aoColumns:[ 
                {"mData": "someTypeId"},
		{"mData": "someTitle"},
		{"mData": "dimensions"},
		{"mData": "notes"}
	],
	bProcessing: true,
	bRetrieve: true
});

Sample jsonData as below:
{"someTypes":
[
{"notes":"N/A","someTypeId":3,"dimensions":"100x100x100","uom":"mm","someTitle":"Steel Box w/ ABC, XYZ 1000"},
{"notes":"N/A","someTypeId":4,"dimensions":"1200x800x145","uom":"mm","someTitle":"WOOD-SQR-STUFF, 100 x 100"},
{"notes":"Height Varies","someTypeId":5,"dimensions":"1130x1200xXXXX","uom":"mm","someTitle":"Plastic & Wool BOX 130x120"}
]}

Please let me know what has to be done to avoid this error or is there a way to suppress the warning.

Thanks,
Uresh
