UserEngine / LoginEngine + file upload


I’m trying to setup loginengine/userengine for my site, and I’ve added
one extra field to the ‘user’ table, which is supposed to store the
filename of the user’s picture. Now, I have upload_progress/file_column
working on other parts of my site, but when I try to submit a multipart
from within user/edit controller I get the following error message in my
dev. log:

Exception during setup of read_multipart_with_progress: undefined
class/module Role

I’m looking at the source code which is producing this error

But to be honest, I’m not sure where/why this pops up.

Any suggestions?
