That was it!!! I was actually creating a new instance of the cfc when I was
using <cfinvoke>. If I create a new instance using createObject() it also
works the way I intended. Thanks for all the help everyone!
BTW, do we know when this bug is expected to be fixed? It seems
like it's been around for a while.

One thing I think it's safe to say is that this is a page context bug
problem, not an issue between CFINVOKE and createObject(). That said, I
have found some strange behavior in a simple test I put together.
Attached are two files. One is a simple CFC designed to handle an upload
based loosely on the one Walter sent. The other is a test script that uses
the CFC.
The CFC always works when you have a fresh instance -- so, createObject() is
not your issue. However, the CFC SOMETIMES works with a persisted instance
and SOMETIMES does not. I could not believe it was happening, but on my
W2K, CFMXu3 server (using the JRun web server) I find inconsistent behavior,
even when repeating what seems like the exact same case multiple times. If
the request during which you upload the file is the request in which you
instantiate the CFC it works 100% of the time. It seems that if you
instantiate a "fresh" instance, then upload a file using that persisted,
unused instance, it works every time. After that, all bets are off.
I am no expert on the inner workings of CFMX or JVMs, but I suspect it has
something to do with the fact that a persisted CFC instance "holds on" to
the page context, and thus, the form scope. I can be merrily uploading
files with a persisted instance and suddenly I start getting null pointer
exceptions. I figured once they started they would not go away, but that
too did not seem to be true. Perhaps it is too late and more eyes will
expose a silly error in my test case, but I'd be curious to hear if others
have similar experiences.
My suggestion is that when doing file uploads in CFC methods you simply
create a new instance of that CFC during the request in which you are doing
your upload -- that should be fool-proof.
Also, I've seen this mentioned in other public forums, so I think it's safe
to say that there are rumors that Red Sky just might possibly fix the page
context problems once and for all ;)
