Hi all,
Uploads in Cocoon are handled at the servlet level, including a check of
the maximum upload size which raises an exception. This exception is a
major pain because it gives no chance to the application to warn the
user that she exceeded the allowed limit. All we get is an ugly servlet
engine-generated error page.
Rather than throwing an exception, the multipart parser could store in
the request a special implementation of the Part interface,
"InvalidPart" that allows the application to know about it and react
accordingly. For example, the CForms upload widget could show a
validation error in such occasions.
All methods of the Part interface (getInputStream, getName, etc) would
of course throw an exception in InvalidPart, but that exception would
have a chance to be handled cleanly by a <map:handle-errors>
WDYT?
