Hi,
just wondering if anybody knows of a handy way to properly handle the
exceptions that are thrown when a user uploads a file that exceeds the
size limit (or who knows what else can happen)?
The stack trace that I see in such a case is as follows -- and apart
from trying S.addAround I don't see a any place where one could insert
some exception handling:
Message: org.apache.commons.fileupload.FileUploadBase
$SizeLimitExceededException: the request was rejected because its size
(7385713) exceeds the configured maximum (6291456)

I did move to the OnDiskFileParamHolder, but that doesn't make a
difference I guess.
The behavior I want of course is to issue some S.error(...) but go on
displaying the template and preserving the other posted field
contents.
Thanks a lot,
Tim
