Problem with Ajax evaluator

Hi, I am having a problem with ajax. I'm using an evaluator to update some parts of my page, everything going well, except for a few graphics made with the Google charts API. All the callbacks are executed, and executes the rendering code correctly , but the change is not displayed until I make a complete refresh. Any idea what could be happening?

QuestionnaireComponent >> renderGraphicsOn: html

html div id: 'graphics'; with: [
    html heading level: 4; with: 'Score for team'.
   html div id: 'teamsGraphic'; with: [
    self renderTeamsScoreGraphicOn: html.
   ].
   html heading level: 4; with: 'Score for metric'.
   html div id: 'metricsGraphic'; with:[
    self renderMetricsScoreGraphicOn: html
   ]
  ]

QuestionnarieComponent >> renderPossibleAnswersForQuestion: question withIndex: index on: html

html form:[
  (html select)
   id: index asString;
   list: question answers;
   labels: [:each | each text];
   selected: (questionnaire choiceForQuestion: question) answer;
   callback: [:value | selection := value];
   onChange:
    ((html evaluator)
     triggerFormElement: index asString;
     callback: [:script |
      questionnaire answer: question with: selection by: self session user username.
      (script element)
       id: 'personDiv' , index asString;
       update: [:r | r text: 'answered by ' , (questionnaire choiceForQuestion: question) person].
      (script element)
       id: 'scoreDiv';
       update: [:r | self renderScorePanelOn: r].
      (script element)
       id: 'submitButton';
       update: [:r | self renderEvaluateButtonOn: r ].
      (script element)
       id: 'teamsGraphic';
       update: [:r | self renderTeamsScoreGraphicOn: r].
      (script element)
       id: 'metricsGraphic';
       update: [:r | self renderMetricsScoreGraphicOn: r].

      (script element)
       id: 'submitButton';
       update: [:r | self renderEvaluateButtonOn: r ]])]

QuestionnaireComponent >> renderTeamsScoreGraphicOn: html

html render: teamsComponent

It sounds like the Google Charts API is not evaluated.

What version of Seaside are you using? What platform? What did FireBug say?

Thanks Lucas, I just found the error... was me. jeje

The first element that I was trying to update, did not exist in that moment, then the others updates where not being executed, and Firebug does not report any bug. I don't know if should do it.

Regards

Sebastián

Did you enable that FireBug should report all JavaScript errors and warnings?

Sometimes this is not enabled.
