Error: this._data[i] has no properties

Error comes in following code:
--:ACTIVE.TEXT.TABLE:---
var defaultResponse = table.response;
table.response = function(data){
alert("Recs:");
defaultResponse.call(table, data);//This Line Gives Error
//Datalen=table.getCount();
/*for(var x=0; x< Datalen; x++) {
fieldcolum0 = table.getText( x, 0);
fieldcolum1 = table.getText( x, 1);
fieldcolum2 = table.getText( x, 2);
fieldcolum3 = table.getText( x, 3);
fieldcolum4 = table.getText( x, 4);
fieldcolum5 = table.getText( x, 5);
fieldcolum6 = table.getText( x, 6);
GridData.push([fieldcolum0, fieldcolum1, fieldcolum2,fieldcolum3, fieldcolum4, fieldcolum5,fieldcolum6]);
}*/
}
I m using paging in grid and caching 2 pages (60 records) in grid which is some portion of my data from db.
while i m going to gridpage3 which loads data from db and then grid doesn't rendered and throws Error: this._data[i] has no properties error

I had Solved it

set Row Property for Grid on Data Load Complete

table.response = function(data){
           Grd.setRowProperty("count", i);
           defaultResponse.call(table, data);
          .
          .
          .
    }
