Rails - Jul 2005 - Undefined method 'keys'

Hey all,

I am overloading the save method in an ActiveRecord::Base class. The
paste of my code is here : http://rafb.net/paste/results/50i2Sy74.html

I cannot seem to get it to work though, even without all the file junk
and just a
def save
  super
end

I get the error 
undefined method ''keys'' for nil:NilClass

Thanks for any help I am looking into the ActiveRecord now,
Paul

It looks like it is trying to call the "keys" method on a nil hash. 
So
I would look for such a a call on the line number in the stack trace,
and find out why the hash is nil.
