[Seaside] Potentially nasty seaside bug.

  I don't understand what you mean by "never referred to again". Your 
#renderContentOn: incudes this:

html form: [
       html text: 'enter value here: '.
       html textInput
          value: self inputValue;

          callback: [ :value | self handleValue: value].
     html break.
      html text: 'result:'.
       html textArea
          value: self outputValue;
         rows: 10;
         columns: 60.
         html submitButton with: self inputValue asString, ' factorial'.

which definitely sends #inputValue and #outputValue. And your 
#handleValue: method sends both #inputValue: and #outputValue:. So maybe 
it would be good to boil this example down to the bare minimum neeeded 
to reproduce the problem.
