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

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
