Ok Guys, I have fixed it
OverrideDataTableModel:
/**
* methdo returning the desired data
*/
public JSONObject getResponse(GridDataSource source){
response.put("sEcho",
request.getParameter(DataTableConstants.ECHO));
int records = source.getAvailableRows();
response.put("iTotalDisplayRecords", records);
response.put("iTotalRecords", records);
String displayStart =
request.getParameter(DataTableConstants.DISPLAY_START);
int startIndex=Integer.parseInt(displayStart);
String displayLength =
request.getParameter(DataTableConstants.DISPLAY_LENGTH);
int rowsPerPage=Integer.parseInt(displayLength);
int endIndex= startIndex + rowsPerPage -1;
if(endIndex>records-1) endIndex= records-1;
source.prepare(startIndex,endIndex,sortModel.getSortConstraints()
);
JSONArray rows = new JSONArray();
for(int index=startIndex;index<=endIndex;index++)
{
JSONObject cell = new JSONObject();
Celebrity obj = (Celebrity) source.getRowValue(index);
List<String> names = model.getPropertyNames();
for (String name: names)
{
Object val;
if(name.equals("view")){
//We add the content of the extra column
//We use the ComponentResources service, for
creating an EventLink
//We will add the id of the current element as
a context of the
event link
val = String.format(" Update <%s>
",linkSource.createPageRenderLinkWithContext(DataTableAjaxWithNewColumn.class,obj.getId()).toURI());
}
else {
PropertyConduit conduit =
model.get(name).getConduit();
String cellValue;
Class type = conduit.getPropertyType();
val = conduit.get(obj) != null ?
conduit.get(obj) : "";
if
(!String.class.equals(model.get(name).getClass())
&&
!Number.class.isAssignableFrom(model.get(name).getClass()))
{
Translator translator =
translatorSource.findByType(model.get(name).getPropertyType());
if (translator != null)
{
val = translator.toClient(val);
}
else
{
val = val != null ? val.toString() : "";
}
}
}
cell.append(name, val);
}
rows.put(cell);
}
response.put("aaData", rows);
return response;
}
