Hi,

I’ve been developing a RoR application for a couple of months now, and  
haven’t made any recent upgrades (Aptana RadRails in MyEclipse IDE).  
All of a sudden, I’m getting the following warning messages:

c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active\_record/  
xml\_serialization.rb:278: warning: Object#type is deprecated; use  
Object#class

I’d appreciate if someone could tip me on how to fix this. Thanks,

Chris.
