[jQuery] Form Plugin and File Uploads (form.submit() is not a function)


Hi,
Just started to play with jQuery and Form Plugin. And now I have some
problems :)
I want to upload a file using jQuery and Form Plugin. When I'm trying
to upload a file an error occurs, saying:
"Error: form.submit is not a function
Source File: jquery.form.js
Line: 292"
If i don't include a file the form submit seems to work fine. Anybody
knows what I'm doing wrong?
An example can be seen here:

(Click the link "Ladda upp en ny bild" to slide down the upload form)
FYI: The PHP file being called is just a dummy file, echo-ing: "<img
src="../images/bild1.jpg" width="100" height="91" alt="Bild1"
style="display:none" />"
Thanks,
Niklas
