I'm trying to export a POI worksheet as a download link in my wicket page.
The link sets the responsepage to a download page in which

You can do that directly from your link, without an intermediate page.
At least it works with buttons with a form, but I don't think a link
makes any difference:
protected void onSubmit() {
WebResponse r = (WebResponse)getRequestCycle().getResponse();
r.setContentType("application/octet-stream");
r.setHeader("Content-Disposition",
"attachment; filename=\"data.abc\"");
r.write("data");
getRequestCycle().setResponsePage((WebPage)null);
}
See wicket.examples.displaytag.export.Export for a more complete example.
This is what I am using with wicket 1.1.1.
