Thanks Bruno.
Now I do this.
_____________________________________________________________
HttpServletResponse response =
(HttpServletResponse)context.getExternalContext().getResponse();
response.setHeader ("Content-Disposition","attachment;filename=\"mae.csv\
"");
response.setContentType("text/csv");response.getOutputStream().write(sbExcel.toString().getBytes()); response.getOutputStream().flush(); response.getOutputStream().close(); *StateManager stateManager = (StateManager)context.getApplication().getStateManager(); stateManager.saveSerializedView(context);* FacesContext.getCurrentInstance().responseComplete(); _____________________________________________________________ But I get an error - see attached image (image.jpg).
