I am seeing the “warning: Object#id will be deprecated; use  
Object#object\_id” message coming from ActionController in my apache  
error log. I do not see it anywhere else – neither the production nor  
development rails logs.

Something is calling dom\_id with something that is not an active record  
I guess. How can I track down who is doing this?

I’m running Rails 2.1.

Thanks
