Subject: Re: Continuation in web (Seaside clone)

Done! :)
I founded an ugly solution (closures instead of continuation). It works, 
looks like:

All other components are the same as earlier, i just a little changed 
the 'View'.
To complete edition user should 3 times enter something in Wizzard-like 
dialogs.

WITH CONTINUATION IT SHOULD LOOKS LIKE:
class View < Panel
  def initialize editor
    view= Label.new self, 'Value'
    Button.new(self, 'Edit') {
      first = call(editor)
      second = call(editor)
      third = call(editor)
      view.text = first+second+third
        }
    end
end

WITH MY UGLY SOLUTION IT LOOKS:
class View < Panel
  def initialize editor
    view= Label.new self, 'Value'
    Button.new(self, 'Edit') {
      call(editor) { |v|
        first = v
        call(editor){ |v|
          second = v
          call(editor){ |v|
            third = v
            view.text = first+second+third
                    }
                }
      }
        }
    end
end
