accessing the changed? method for an overridden attribute

[tonypm]

I am using rails 2.3, and have overridden an attribute.

I am building a before_save callback, and would like to check if the attribute has changed - but can't figure out a way to do this.

Sorry - silly Friday afternoon question.  changed? method applies to the object as a whole, to test if an attribute has changed, should have used attrname_changed?  which of course hasn't been overridden.
