Hi Niphlod - I modified my response.stream call to include the filename
argument. When I call the controller, the file does get downloaded.
However, when ajax calls the controller, the file isn't downloaded.
@Leonel, a simple link, like A('download tar file', _href='%?attachment' %
path_to_download_file) won't work because the file to be downloaded doesn't
exist at the time the link is created. It needs to be generated on the fly.
