A trick I use sometimes might help.
Make a js that copies your filefield inof to a hidden form element. Then
use CF to check the value of that hidden field (aptly named to tie it with
the sister filefield if you're doing multiple uploads) ... the field will
contain the information that you see in the filefield, so you should be able
to check the value of the contents... only accessing the actual file
variable containing the tmp information when you need to process an upload.
only caveat to this... I havent' tested with a Mac so I can't promise you
that mac js will behave the same way that IE 5.x js has been for me...

|Ok, so MacIE5 puts a return character in all form fields
|(explains why I was
|getting weird stuff doing updates on formfields pulling stuff from a
|database).
|
|Is there any way to stop Coldfusion thinking that the return
|is an ACTUAL
|file?
|
|As I tried to explain before, it seems that CF sees the form
|field as not
|being empty, creates a temp file, saves the supposed file to
|the temp file,
|and replaces the content of the form field with the temp file name. So,
|besides checking the length of the temp file, is there anyway
|to actually
|prevent the upload in the first place?
|
|this is driving me spare...
