in which order are the validations executed that apply to the same  
attribute.  
Say I have this code in my model:

validates\_presence\_of :password  
validates\_confirmation\_of :password, :message =\> “must match confirm  
password”, :if =\> Proc.new { |u| !u.password.blank? }

1. Are the validations executed in the order I coed them in the  
model’s file?  
Or is it undetermined, and I should not rely on any order?

2. Is this behaviour the same in 2.x and 3.x?

thanks,
