code looks ok, interesting.
there are two things we can do: a) you can create a quickstart that
reproduces the problem
b) you can set a breakpoint in fileuploadfield#getfileupload() and see
why it returns null
a couple of other notes:
since you are getting fileupload yourself there is no need to give the
field a model
you are passing in userprofile directly into the panel, most likely it
needs to be a loadabledetachablemodel that can load it from the db.
