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. See some examples: http://www.7thweb.net/wicket-jquery-ui/kendo/datatable/CommandsDataTablePage;jsessionid=2926A68F12DAE4CAC910C18699676209?0 https://doc.codelutin.com/cantharella/xref/nc/ird/cantharella/web/utils/data/TableExportToolbar.html François François Meillet Formation Wicket - Développement Wicket Le 6 nov. 2014 à 13:07, suvojit168 <[email protected]> a écrit : > Francois Meillet wrote >> try >> List<IExportableColumn<AffiliateModel, ?>> columns = new >> ArrayList<IExportableColumn<AffiliateModel, ?>>(); > > Hi François, > > Thanks for reply.
