William,
Thank you for your response, but I just solved the problem. It appeared that my proces was too busy, so the view didn't get any time to update. I had created a proces function instead of making use of the event handlers. Once I corrected this, the parameters are updated in the view too.
Anyway, thank you for your response
Peter
