>             Project: Commons FileUpload
>          Issue Type: Bug
>    Affects Versions: 1.2.2
>         Environment: Tomcat 6.0.24
>            Reporter: Björn Agel

> I wrote a ProgressListener to visualize the upload of a file.
> The Listener works as expected as long as the sizeMax-value of the ServletFileUpload
class is not explicitly set.
> If it is set the update()-method of the ProgressListener has ZERO-values for bytesRead
and contentLength ... whats wrong here?
