Reseting and reusing of upload-widgets

[Bj�rn Voigt]

Moin,

i use an upload-widget (cocoon-2.1.5) in my cforms,
but I need it once more, but I cant set the value to
null to reset it for reuse.

setValue is not implemented and throws an exception.
It allready possible to reset it? If not, Is it possible
that you add an method like to Upload.java

public void reset() {
        this.part = null;
}

Thank you

Bj�rn
