datatable ajax with new column
Hello All,
I am using datatables component in similar way which was presented here:
http://tapestry5-jquery.com/other/datatableajaxwithnewcolumn but I am
getting sam exception. I have updated datatables to the newest version but
it didn't help. Do you know what is causing this problem?
Many thanks for any answer.

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;
}

Hi Manu,
You were partially right I think :). It's true you don't have to override
data model, but if you try to ad custom column like you are doing in your
example for instance any action button than it fails in default data model
throwing null pointer exception. Any suggestions?

Normally, with the current SNAPSHOT, you do not have to override the
DataTableModel model. But I am not sure. can you test it ? if it does not
work, I will provide a new sample.
