Ah, stupid me. I just realized that the submit is being caught and handled
using a JQuery .post() so the data isn't actually sent as
multipart/form-data. I guess I need to do a bit more work in the submit
code to make it responsive to the enctype. Can anyone tell me if this just
won't work? The basic difference between the current situation and other
file uploads that are part of the entire application is that, in this case,
the file upload is in the context of a modal 'dialog' rather that a passive
'window'. I think I read somewhere that file uploads are handled using a
stream after the POST is received.
Ragards the except handler, I simply put that there so that I could set a
breakpoint if there was some sort of exception going on. So I do know that
there isn't an exception being swallowed, the code isn't yet complete
because I haven't been able to get the uploaded file to do anything with.
