Processing callbacks on scriptaculous forms

Hello,

I'm getting the "Component not found whilst processing callbacks" error 
for a form that is rendered via scriptaculous. Am I missing something?

Root>>initialize
  super initialize.
  editor := Editor new "Editor just renders a form"

Root>>children
  ^Array with: editor

Root>>renderContentOn: html
  html unorderedList: [
    self items do: [:each |
      html listItem: [
        html anchor
          onClick: (html updater
            id: #editor;
            callback: [:ren | ren render: (editor item: each)]);
            with: 'Edit ', item description]]].

  html div id: #editor

Thanks,
John.
