I need to download a file generated by JasperReports and handle data-arrival. I used GWT Frame.setUrl(..) and I added LoadHandler. If downloaded file has content-type "text/html", LoadEvent is fired. If content-type is "application/xls" browser shows SaveAs dialog, but LoadEvent of GWT Frame is not fired. We need to download html-files and excel-files from JasperReports and handle data arrival event in both cases. Do you have any advice?
