I currently have the same problem. i have to download a rather large file (3MB-12MB) and the file is downloaded correctly, however, the on progress is never triggered, even if i load it over a slow connection.
Ashley , i the manual it says
[quote:1agkx0oh]For long running requests (e.g. downloading a large file), On progress triggers periodically and updates the Progress expression with the state of the request. This is useful for making progress bars for AJAX requests.
Would you kindly specify "periodically"? Does this mean 100of a second, second, 10 seconds?
