[Seaside] SUPeriodical

[squeakman]

Hi,

I have the following code:

html
   script:
      ((html scriptaculous periodical);
      id: 'compositeGraph';
      frequency: 5 seconds;
      on: #renderNextImageOn: of: self ;
      assignTo: 'FLPer').


but my method #renderNextImageOn: never gets called. Do you see anything 
obvious that I am doing wrong?

Thanks,
Frank
