Hey Anthony, i've tried this recipe and it works. In my opinion it's a common task in modern web development to upload files in the "ajax-way". My problem is, as with as other recipes in the book, the modification of a core file of the web2py framework. What happens, if we do an update to a newer version of web2py? I think all this modifications will be lost. What do you think is the best way to handle this problem?
