Error is:  
NoMethodError: You have a nil object when you didn’t expect it!  
You might have expected an instance of ActiveRecord::Base.  
The error occurred while evaluating nil.[]

Client:  
notification\_email.rb model  
class NotificationEmail \< ActiveResource::Base  
self.site = “[[http://mysite](http://mysite)]”  
end

I use the model class to create a new object. Error happens on save.  
def create\_notification  
n = NotificationEmail.new  
n.save  
end

Web service set up is very simple. It basically saves the record to  
the database. I tested it with curl and it works. Anyone has any  
ideas what this error message means?

Thank you!
