OK, I've solved this puzzle (sort of), and it comes back to the
Tutorial code.
The tutorial instructs you to set the External Width of the MIME type
field to 20. However, the model in the source code has it set to 200.
Ah ha! So it is a bug in the tutorial. Oh Janine.... :-)
So, when you run the tutorial source, my MIME type problem doesn't
come up. However, if you look at the database itself after updating a
record without specifying a file for upload, the MIME type does change
to application/octet-stream. Of course, with my MIME type field set
at a width of 20, my application reports an error :)
So my question is; is there a simple solution to this problem, and if
not, why bother with the MIME type field at all?
I don't think any solution is particularly simple. Anything that you
do at this level is going to be hack. Janine and I have been
discussing various ways of handling this nicely, but that is for a
latter step in the turtorial. I guess we need to discuss the "not
simple and too much work" case again.
PS, I just want to use the opportunity to thank Janine for all the
effort that went into this tutorial. It was exactly what I had been
missing, trying to get started with WebObjects. And although this
particular problem has cost me a number of hair follicles and some
lost sleep, I have learned a great deal working my way through it.
Yes! Bravo Janine!

You're correct, that is the error reported. But the problem is that
this happens when I don't want to update that field. With no file
selected in the FileUpload field, the MIME type is still reported
application/octet-stream, when it should be empty. So if I bump up
the field size, the MIME type gets replaced.
