Dear Magnolians
I'm trying to add some functionality to the multipart request filter. The one,
which is configured by default with Magnolia is the CosMultipartRequestFilter.
This filter works fine, but cannot be properly extended since the cos classes
are not open source and some are even private.
So I decided to use the Apache Commons fileupload library as it is used in the
MultipartRequestFilter. I got my extension to work fine for form file uploads
and also for the FCK Editor (e.g. image upload). Unfortunately activation now
fails miserably. Configuring Magnolia to use the "official"
MultipartRequestFilter leads to the same exception:
2010-01-09 14:27:24,651 ERROR

info.magnolia.cms.filters.MultipartRequestFilter.doFilter(MultipartRequestFilter.java:121)
So I must assume that the Apache Commons fileupload library is incompatible
with the activation requests sent from author to public. Can anyone confirm
this - or even better: does anyone have a workaround for it?
Thanks!
