Upload Fields

[José de Paula Eufrásio Júnior]

Hello again.

I searched google and the list with no much luck so, can someone point
me an example or actual code using the widgets.FileField and
validating/keeping an upload? I want to validate the filename or check
for the mimetype (with a custom FancyValidator), but I really didn't
get how this FileUploadKeeper work. Maybe because I never did a file
upload using a form before :P
