Likely a comma vs. semi-colon in an NSString on a 13" monitor bug. ;-)
If you look at the headers from the request (sent earlier in this
thread) you'll see it.

Ah ha! :-)
What caused this? Is it an iPhone bug?

We found the issue. It was a misplaced comma, instead of a semi-
colon following "multipart/form-data" in the request.
Thanks everyone.

Use a hex editor to look at the raw requests. Years ago there was
a similar problem with IE where the request was missing a ^M/
carriage return after the content boundary. This sounds like a
similar problem: you are receiving a malformed request.
We fixed it by hacking, er cleverly altering, the Apache WO
adaptor to detect the problem and insert the missing byte.

Yeah, it works with a browser and with Flash.
I can get at the content, it's just posted in the 'content' of
the request and not as a form value. I wasn't sure if there was a
way to get at it, but it doesn't seem like it.
Thanks!

But _try_ with a browser. See if you can isolate the problem to
the WO code or the request you are receiving. If it works with
Safari, the problem is not in your code.

FWIW, I get the following when grabbing

.webobjects
.appserver._private.WONoCopyPushbackInputStream@7f9a29 of
length 418147), has NOT been accessed>
I can then write the WOInputStreamData out to disk. Within
that file, I see:
Content-Disposition: form-data; name="Filedata";
filename="image.jpg"
Content-Type: application/octet-stream

If I remove the 'human readable' text, I do get the image. So
my question is, is there a facility within WO to parse this
out?
I am not sure what, but you are doing something wrong or have
something setup wrong or are getting a malformed HTTP request
(user-agent = (CFNetwork/221.5);).
You should just get the binary form value. Try a real browser.

Hi,
seems to be a problem with FileUpload. I never done this
using a direct action.
I think the following may be a good starting point:

Hi,
what did you see using:
NSLog.debug.appendln("headers: " + request().headers());
NSLog.debug.appendln("keys: " + request().formValueKeys());
NSLog.debug.appendln("values: " + request().formValues());

That's just it, when I do that I get a NPE.
If I grab this.request().content() and write it to disk,
I can see that the data is there (Content-Disposition,
etc.).
Other thoughts?

Hi,
you can use request().formValueForKey("Filedata") in
your DirectAction

I have data coming into my app via a POST in a
DirectAction. I can obtain the data via:
(WOInputStreamData) this.request().content()
But that's where I'm stumped. Once I've grabbed the raw
data, how can I extract the form information/data from
it?
Content-Disposition: form-data; name="Filedata";
filename="image.jpg"
Content-Type: application/octet-stream
