Hi, Why does Upload.getValue() first check if it's valid, and if not, simply returns null? This is a problem for validators that want to access the uploaded file (the Part instance).
If I have a required upload field, then submit the form (without uploading any file), the upload widget is invalid (which is correct). Then, when I select a file and submit again (the file will be uploaded) I can't access the part in my validator, as the Upload widget is still invalid. Should there be an alternative method for accessing the part, that doesn't check if the upload widget is valid? This isValid() check before returning the Part is introduced after 2.1.5. Thanks, Bart.
