I have a AJAX based form and when I use send\_file there is no pop-up  
that appears to prompt user to download file… how do I fix this?

Did you Google for that first? It’s a FAQ in Ajax-land, because browsers  
have  
security constraints that prevent JavaScript from manipulating file  
input elements.

The answer is do old-fashioned Ajax that bypasses JavaScript. When a  
form’s  
target field is the name of a 1-pixel

Google for that FAQ to learn how to update your page after the call,  
because I  
forget.
