I’m downloading a file with FileDownloader from a database:
[code]
table.addGeneratedColumn(columnDownload, new ColumnGenerator() {
public Object generateCell(Table source, final Object itemId, Object columnId) {
final Button download = new Button();
download.setIcon(new ThemeResource(“Download.png”));
StreamResource resource = downloadFile(itemId.toString());
if (resource != null) {
final FileDownloader fileDownloader = new FileDownloader(resource);
fileDownloader.extend(download);
}
return download;
}
});
[/code]It works with all browsers except of the iOS browser (iPad). I get this error:

Unfortunately, the log file gives me no more information about the error.
What can I do?
