Hi,

I wish I could display that tiny little red star on an Upload field defined as below, would it be possible? I'm using Vaadin 8.

final Upload upload = new Upload("Picture 1", new MyUploadReceiver());
upload.setImmediateMode(false);
upload.setButtonCaption(null);
upload.setIcon(VaadinIcons.FILE_PICTURE);

Thanks,
Chris
