Feature Request: Extra field for a custom upload Status message

[GoogleCodeExporter]

Hi
We use your nifty lib to upload Excel files in a custom format.
Now, there are several possible format errors we want to present to the
user, but currently gwtupload supports only one single ERROR Status.

I would propose an extra (String) field 'StatusMsg' where the client can
put some custom Error message (or Code), similar to the HTTP Protocol.
Would this be possible?
Else my coworker wants to switch to the upload control provided by ext-gwt:
http://www.extjs.com/deploy/gxtdocs/com/extjs/gxt/ui/client/widget/form/FileUplo
adField.html
(But I doubt it provides the same power as gwtupload)
thx,
Laurent

Hello laurent

I see at least two solutions to your problem, you can put in your interface a 
textbox
which can be read when the file input changes (use 
`addOnStatusChangedHandler`),  then:
- Add this value to the query string
`setServletPath(".../myservlet.upld?userinput=whatever")` and read it in the 
server
side with `request.getParameter("userinput")`
- Or add a hidden input to the uploader `add(new Hidden("userinput", 
"whatever"))`
which will be available in the server as a element in the `FileItem` collection

About GXT, I think it would be possible to use gwtupload if you are able to 
wrap its
widget and implement `IFileInput` which uses `Uploader` but I've not play with 
it. 

Regards
Manolo

It is not necessary to add anything to the library because the 
`uploader.add(Widget)`
method does it.

Hope this helps you

@Override
 public String executeAction(HttpServletRequest request, List<FileItem> sessionFiles) throws UploadActionException {
    String response = "";
    int cont = 0;
    for (FileItem item : sessionFiles) {
      if (true == item.isFormField()) {
         // handle a normal form field
      } else {
         // handle the file
      }
