OK. I used debugger and found that 'setax and 'setbx' are nil instead
of being assigned the strings in 'setA.split(" ")' and setB.split(" ").

Using debugger I verified that setA has the proper string value entered
at the form.

Even if I change the code to setax = setA, setax is always nil.

Does the fact that setA and setB are in the Attribute-Accessor list make
a difference in the way I should assign other variables their value?

Here is the code:

class Search < ActiveRecord::Base
belongs_to :project
has_one :user, :through => :project

attr_accessor :setA, :setB, :setAList, :setBList, :google
before_create :setup_data
before_save :setup_data
def setup_data
debugger
setax = []
setbx = []
setax = setA.split(" ")
setbx = setB.split(" ")

Thanks!
