> Key: TAPESTRY-687
> URL: http://issues.apache.org/jira/browse/TAPESTRY-687
> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 4.0
> Reporter: Chris Norris
> Priority: Critical
> Fix For: 4.0.1
> Attachments: patch.txt
>
> The org.apache.tapestry.form.validator.Required class can be used for the
> Upload component, but does nothing. The object parameter passed in to
> validate() will always be a non-null UploadPart, but will return a getSize()
> of 0. So if a user enters "alsdkfjlaskdfj02/:" as a file path in an upload
> component with validators="validators:required", nothing will be marked as
> errored.
> I'm not sure if the Required validator is supposed to work for all things,
> but I see that it has different conditions for Strings and Collections. I
> created a patch that works with UploadPart objects as well.
