FileUploadException is masked behind WicketRuntimeException and not handled by
a Form
-------------------------------------------------------------------------------------
Key: WICKET-3078
URL: https://issues.apache.org/jira/browse/WICKET-3078
Project: Wicket
Issue Type: Bug
Components: wicket, wicket-extensions
Environment: Widnows, Jetty 7
Reporter: Ivan Vasilev
I have a org.apache.wicket.markup.html.form.Form fileUploadForm, which has:
fileUploadForm.setMultiPart(true);
fileUploadForm.setMaxSize(Bytes.kilobytes(150));
When the form is submitted with a file larger than 150K the following methods
are called:
fileUploadForm -> handleMultiPart ->
ServletWebRequest.newMultipartWebRequest((Bytes maxsize) and inside it
try
{
return new MultipartRequest(getHttpServletRequest(),
getFilterPrefix(), maxsize);
}
catch (FileUploadException e)
{
throw new WicketRuntimeException(e);
}
When the file size exceeds the maximum allowed a FileUploadException is thrown,
however it is immediately caught and "masked" in a WicketRuntimeException.
Inside the handleMultiPart method of the Form there is a catch block for
FileUploadException, but the original exception is no longer of type
FileUploadException and in this case the form fails to handle it. The result is
that instead of an error message informing the user of exceeded limit a wicket
stack trace page is displayed.
I'm not sure if this is part of wicket or wicket-extensions, because it
involves classes from the both modules.
