> Key: TAPESTRY-125
> URL: http://issues.apache.org/jira/browse/TAPESTRY-125
> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 3.0
> Environment: Operating System: Windows NT/2K
> Platform: PC
> Reporter: Michael Li
> Fix For: 4.0.1
>
> In Tapestry v3.0-beta-3, submit a form with "Upload" component without
> actually
> choosing any file will cause
> "java.lang.ClassCastException" when browsing in Opera v7.23.
> It works fine when browsing in IE6 and Mozilla Firefox 0.8.
> The same issue exists in Workbench example web app (in Opera) - though in IE6
> and Mozilla, it reports another exception, but that is another bug in the
> <input
> jwcid="@Upload" .../> component - should be <input jwcid="[EMAIL PROTECTED]"
> ...
> />.
> Stack Trace:
> *org.apache.tapestry.multipart.DefaultMultipartDecoder.
> getUploadFile(DefaultMultipartDecoder.java:276)
