Re: How to use CSVDataExporter
Hi Suvojit, I don't know CSVDataExporter but I noticed that the second bounded type parameter was a wildcard and not a defined type. I use Wicket 7 where there are only 2 parameters.

Re: How to use CSVDataExporter
Hi François, Suvojit Actually the Wicket Kendo UI's DataTable (first example) is using a custom CSVDataExporter (largely inspired - not to say copy/paste - from the original). But it can still itself be used for inspiration... Source: https://github.com/sebfz1/wicket-jquery-ui/blob/master/wicket-kendo-ui/src/main/java/com/googlecode/wicket/kendo/ui/datatable/export/CSVDataExporter.java Best regards, Sebastien On Thu, Nov 6, 2014 at 2:37 PM, Francois Meillet francois.meil...@gmail.com wrote: Hi Suvojit, I don't know CSVDataExporter but I noticed that the second bounded type parameter was a wildcard and not a defined type.

Re: How to use CSVDataExporter
We have IExportableColumnT, S
where T is the type of each row in the table.
where S is the type of the sort property of the table.
and the method
public T void exportData(IDataProviderT dataProvider,
ListIExportableColumnT, ? columns, OutputStream outputStream)
try
ListIExportableColumnAffiliateModel, ? columns = new
ArrayListIExportableColumnAffiliateModel, ?();

Hi,
I am trying to export data to csv in my wicket pages. I am using
CSVDataExporter for this purpose. Due to some constraints I am not using it
in conjunction to ExportToolbar. There is a link and on click of the link I
am trying to call exportData() on instance of CSVDataExporter.
I am using AbstractExportableColumn for columns writing data to columns.
However I am getting a compile time error on exportData. Follwoing is the
code (excelDataImport is the link here ):
excelDataImport.add(new AjaxEventBehavior(onclick) {
private static final long serialVersionUID = 1L;
protected void onEvent(AjaxRequestTarget target) {
ListIExportableColumnlt;AffiliateModel,
String, String columns = new
ArrayListIExportableColumnlt;AffiliateModel, String, String();
columns.add(new
AbstractExportableColumnAffiliateModel, String,
String(new ModelString(Affiliate Name), name) {
@Override
public IModelString getDataModel(
IModelAffiliateModel
arg0) {
// TODO Auto-generated method
stub
return null;
}
});
try {
new CSVDataExporter().exportData(new
AffiliateDataProvider(null),
columns, new FileOutputStream(test.xls));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
The error message is : The method exportData(IDataProviderT,
ListIExportableColumnlt;T,?,?, OutputStream) in the type CSVDataExporter
is not applicable for the arguments (AffiliateDataProvider,
ListIExportableColumnlt;AffiliateModel,String,String,
FileOutputStream).
I think I did it all correctly (as per whatever knowledge I could get on
this subject), am I doing something wrong here?
Also, can anyone share with me some sample examples and description/details
for CSVDataExporter? I have gone through example in DataTablePage.java in
wicket example but that is using DataTable and ExportToolbar.
Thanks,
Suvojit
