Roll your own link:
Link<File> downloadLink = new Link<File>("yourID",
yourModelThatReturnsAFile) {
private static final long serialVersionUID = 1L;
@Override
public void onClick() {
File file = getModelObject();
if (file.exists()) {
IResourceStream rs = new FileResourceStream(file);
getRequestCycle().setRequestTarget(new
ResourceStreamRequestTarget(rs));
} else {
error(getString("nonexistent-file"));
}
}
};
That code is mostly copied from DownloadLink.
