It is true that in this case, I'm binding to NSData in both instances
where I was having problems with it. But have a look at my more
recent post about how I resolved it... cause in my case, I would sure
classify it as a problem with Safari and uploads in general, and not
WebObjects.

I believe this is related to the issue of streaming vs non-
streaming file uploads ... If you are setting your request encoding
to, for instance, UTF8, there's a bug somewhere along the chain
(maybe in Wonder, maybe in WO, I haven't looked much) that if you
bind to an NSData, the data will have already been consumed by the
time it gets back to the WOFileUpload component, which gives a
totally obtuse error message about it. I remember I looked into
this some a few months back, but didn't spend much time on it ...
Streaming to file paths works, and I think input/output streams
work. I /think/ it's just binding to an NSData doesn't? I'm not
positive about which of those do and don't work, offhand, though ...

Hi Clark,
I know there is some stupid hack that I don't really understand
that fixes your particular problem (No form data left for
WOFileUpload). You can set a system property in the following way:
System.setProperty( "WOUseLegacyMultipartParser", "YES" );
and the problem will probably go away. Be warned though, there
are some places where this seems like a bad idea. I recently lost
a good half day trying to get AjaxUploadComponent to work. The
key to fixing it? Remove the line I just mentioned above.
Does anyone on the list actually understand the underlying issues
here? I've always been curious, but never had time to dig.

I should also mention... my enctype is set to "multipart/form-
data", and I get a stack trace that says:
