misleading update

test case fragment

      puts "in change_state update_attribute state_id to #{new_state.id}"
      result = update_attribute :state_id, new_state.id
      puts "change_state result is #{result}"
      puts "in change_state #2 state id is #{self.state.id}"



output fragment of the test case:

in change_state update_attribute state_id to 28
change_state result is true
in change_state #2 state id is 26
