//Fetch method

//toRecord() -- using beanhelper we create JS object and set it to the ListGridRecord.


	public static ListGridRecord[] toRecords(DataPagedList dataPList, TransferObjectInfo beanInfo)
	{
		DataPagedListBeanHelper dataPagedListBeanHelper = new DataPagedListBeanHelper(beanInfo);
		List<Object[]> rows = dataPList.getDataList();
		ListGridRecord[] records = new ListGridRecord[rows.size()];
		for (int i = 0; i < records.length; i++)
		{
			JavaScriptObject jso = dataPagedListBeanHelper.createJSOFromBean(rows.get(i));
			records[i] = new ListGridRecord(jso);
		}
		return records;
	}

As we dont use bean, not able to serialize the data, I guesss. any suggestion on this
