I have button which works:

    Button options = new Button("sheets", new StringResourceModel("sheets", null)) {

        private static final long serialVersionUID = 1L;

        @Override
        public void onSubmit() {
            setResponsePage(new TournamentOptionsPage(tournament, table) {

                private static final long serialVersionUID = 1L;
            });
        }
    };

now I want to replace this button with downloadLink:

        add(new DownloadLink("sheets", new AbstractReadOnlyModel<File>() {
            private static final long serialVersionUID = 1L;

            @Override
            public File getObject() {
                File tempFile;
                try {
                    tempFile = PdfFactory.createSheets(WicketApplication.getSheetsPath(),
                            tournamentService.getSchedule(table, tournament), table);
                } catch (Exception e) {
                    e.printStackTrace();
                    throw new RuntimeException(e);
                }
                return tempFile;
            }
        }, new StringResourceModel("sheets", null)).setCacheDuration(Duration.NONE).setDeleteAfterDownload(true));

but here I have problem with StringResourceModel and when I push link I got exception:
