I created the class AJAXDownload and copied your code. Then I added the
AJAXDownload to my download button like this:
@Override
public void onSubmit(AjaxRequestTarget target, Form form) {
target.add(feedback);
final SlaReportModel slaReportModel =
(SlaReportModel)form.getModelObject();
if(!slaReportModel.isEmpty()){
download = new AJAXDownload() {
@Override
protected IResourceStream getResourceStream() {
return new FileResourceStream(new
org.apache.wicket.util.file.File(createFileForDownload(slaReportModel.getTxtDatumVon(),slaReportModel.getTxtDatumBis())));
}
@Override
protected String getFileName(){
return filename;
}
};
this.add(download);
download.initiate(target);
}else{
error("Sie m?ssen den Zeitraum angeben!");
}
}
It works fine :) thanks for your help.
Mit freundlichen Grüßen
