I can save one Outline and it works fine, but if two objects are being save, target turns up nil.

## controller action

if params.has_key?(:new_outline_items)
  params[:new_outline_items].each do |attributes|
    @current_course.outlines << Outline.new(attributes.merge!(:account_id => @current_account.id))
  end
end
@current_course.save!

## Model

after_create :set_outlined

def set_outlined
  target.update_attribute(:outlined,true)
end

## error [plain]
NoMethodError (You have a nil object when you didn't expect it!
The error occurred while evaluating nil.outlined=):
    /app/models/outline.rb:10:in `set_outlined'
