> A ProgressListener doesn't always get informed when a new part is found by
> the MultipartStream. This is most easily replicated by uploading small files
> (a few bytes in size). The listener will be correctly informed about the
> content length and the total bytes uploaded but it will be told that it is
> currently working on item 0. This causes an issue when this count is used to
> detect a form has been submitted with no file.
> This has a simple fix to the org.apache.commons.fileupload.MultipartStream
> (patch will be attached), when the items count is incremented the listener
> needs to be notified.
