Hi
as per the PDF provided
>>JSON data is handled in a fashion very similar to that of xml data. What is important is that the definition >> of the jsonReader matches the data being received datatype: json, (or jsonstring)
Some thing is wrong in here
var data = {
       “total”: “1”,
       “page”: “1”,
       “records”: “2”,
       “rows” : [
         {“id” :”1″, “cell” :[“cell11”, “cell12”, “cell13″,”cell13”]},
         {“id” :”2″, “cell”:[“cell21”, “cell22”, “cell23″,”cell13”]},
       ]
      };
Researched and found that changing  datatype : “jsonstring”, TO datatype : “json”,  WORKED
I am pretty sure some bug has squeezed in some where…Â
