I just skimmed over it, so this may not be it, but something to check out.
i.e. you change the call like this (removed "form."):
<cfinvokeargument name="formField" value="aFile">
don't think CF expects that form prefix, it expects a string of the field
name.
again, not sure that is your issue, but jumped out at me.

Subject: [DFW CFUG] Problem with a CFC for uploading a file
Ladies and Gentlemen,
I hope someone can possibly provide some direction or help on this.
Trying to create a simple file upload with a CFC doing the processing.
Simple business rules.
1) Restrict the file type to Word
2) Upload one file (not multiples)
3) Assume the user will have Word files named with unacceptable special
characters .. spaces, #, ! etc.
4) Ultimately plan to capture additional information along with the
renamed
filename into an SQL Server database to present the user an option to
click
n view on a page. (that is after I get past this.)
I had created a simple couple .cfm's that worked, but wanted to move it to
a .CFC and invoke it from the action page. I thought it would be a simple
process, however, that has not been the case.
My attempts failed. So I started doing some Googling.
In the process I stumbled on a snippet of code associated with Farcry.
It
appeared to do alot of what I would like to achieve, but as this was my
first foray into a serious CFC I wanted to follow a piece of working code
to step through and follow.
My attempt succeeds in uploading the file, but ERRORs at the point where I
attempt to identify the filename (using makeunique) to ensure it is
unique.
I have searched the web, and nothing seems to address this issue.
I have checked all the CF books I have and have not had any success.
As noted above the app fails after successfully uploading and saving the
file to the destination folder.
The error "Element SERVERFILE is undefined in CFFILE." implies to me that
it recognizes the CFFILE object but not the SERVERFILE. I have tried
lowercase, uppercase, camel case. I have tried both FILE vs CFFILE upper
and lower case. Same result.
My swag on this is it almost seems like the serverfile is referencing the
.tmp file that has been moved to the DESTINATION folder and the undefined
is a result of nothing there. Or that I am using incorrect but verified
the FILE Attributes in CF MX & Web Application Construction Kit, pg 1024
and again on the Adobe site.
It appears from the research that the file is really uploaded to
...\wwwroot-tmp\neoxxxxx.tmp directory
I am testing this on a WinXP Pro running PWS and developers edition of
Coldfusion MX7
CF version 7.0.0.91690
My folder structure is:
/fload
/fload/docs
My two CFM and the CFC files are as follows.
I really suspect it is a SUP problem.. Stupid User Problem.
Any suggestions or ideas would be greatly appreciated.
Thanks in advance
