Instance variable scope

[John Wells]

Guys,

I've read the NKS cover to cover, but think I might be misunderstanding scope.

For example, in the lastest (git pull; rake) version of shoes, this code:
#############################
class MyApp < Shoes
  url "/", :index
  url "/next", :next

  def index
    @x = edit_line
    para(link("next", :click=>"/next"))
  end

  def next
    begin
      alert (@x.text)
    rescue Exception=>e
      puts e
    end
  end
end

Shoes::app
#############################

Outputs "undefined method `text' for nil:NilClass" on the console. So
@x is nil. However, if I read NKS correctly, especially page 36, @x
should still exist and the text should be accessible.

Can anyone explain why this is happening?

Thanks,
John
