Not sure... but could you try something like:
DownloadLink downloadLink = new DownloadLink("link_id", new
AbstractReadOnlyModel<File>(){
public File getObject() {
return this.linkModel;
};
},"myfile.xxx");
downloadLink.setOutputMarkupId(true);
and make linkModel a member variable? This way file will be "refreshed".
Best,
Ernnesto
