Hi Jeff, thanks for your reply!
I found the article here:
http://www.simonecarletti.com/blog/2009/11/re-raise-a-ruby-exception-in-a-rails-rescue_from-statement/
And he mentions that re-raising does not work since rails won't catch it
anymore..
has this been changed since?
I generally thought there might be a better way, as usually re-raising
exceptions is considered to be bad :)
Thanks a lot,
Christoph
