Hi,
I'm debugging an app and can't find the exact cause of loosing the
contents of a file being uploaded. I know WO is capable of uploading
files, that's not the issue, even I tested using XCode with WO5.3 in
Tiger, Eclipse with WO5.4 in Leopard and finally using Eclipse with
WOnder 5.4 in Leopard. All worked with no problems. If I needed to
grab the file contents I could do it either in createRequest,
dispatchRequest or in the DA method or the action object-method in
case I wanted not to use DAs.
But then I moved to the non-working app and I can see file contents
in createRequest method --I can even save the file-- but as soon as
execution gets to dispatchRequest, and though I get a valid object
when I issue the call InputStream input =
part.formDataInputStream(); --input is valid object-- I don't get
any data from the call input.read(buffer, offset, length - offset);
or input.available() all I get is a -1 which means there's no data.
I don't have an awake method, that I think is the next method in
execution after createRequest gets called and before dispatchRequest
gets called too.
Does anybody had experienced something simliar? or have a clue of
what could be causing to loose data?. I checked the encoding for the
WOComponent and is set to UTF-8, so defaultFormValueEncoding=UTF-8
and formValueEncoding=UTF-8 are the same.
I'm not sure where, but I think the encoding is getting changed. Are
you using Wonder in this app? If yes, add this to the Properties file:
er.extensions.ERXApplication.DefaultEncoding= UTF-8

Here's the request that doesn't upload, see if someone can see it
