Code like the following worked fine under Rails 2.0.2 but now throws an  
exception under Rails 2.1.0. Has anyone else had this issue?

class BugTest \< ActiveRecord::Base  
def set\_name(value)  
send(“name=”, value)  
end  
end

Here’s the exception…

NoMethodError: You have a nil object when you didn’t expect it!  
You might have expected an instance of Array.  
The error occurred while evaluating nil.include?  
/vendor/rails/activerecord/lib/active\_record/dirty.rb:126:in  
`write\_attribute’

I came across this upgrading a site to Rails 2.1. In my case it was  
attribute change tracking stuff in Rails not playing nicely with the  
acts\_as\_versioned plugin which does something similar. The latest  
version of the plugin sort this, grab it with something like “script/  
plugin install git://github.com/technoweenie/acts\_as\_versioned.git”.

Do you know how this problem was solved or shall I dive into the  
acts\_as\_versioned code?

I think acts\_as\_versioned was extending ActiveRecord with its own  
changed\_attributes collection. I was hoping you’d be using the plugin,  
but if not then yeah, I guess you could jump in the code.
