Hi, Here is code to export excel;
Link linkExcel = new Link("linkExcel") { public void onClick() { getRequestCycle().setRequestTarget( new ComponentRequestTarget(tableContainer) { @Override public void respond(RequestCycle requestCycle) { ..... WebResponse wr = (WebResponse) getResponse(); wr.setContentType("application/vnd.ms-excel; charset=utf-8" ); wr.setCharacterEncoding(Constants.ENCODING); wr.setHeader("content-disposition", "attachment;filename=" + Constants.DEFAULT_EXCEL_FILE); } } It works great. *Problem steps *: 1. Click excel link and get the excel file - great ! 2. Click a modalwindow link (Ajax) gets "*Page Expired"* error. Any suggestions on *step 2* ? Thanks.
