[Seaside] How to use PTFactory>>evaluator for select list entry (beginners question)

[Gerhard Obermann]

Hi Sabine and welcome!

Try something like:

 script prototype element id: 'formB'; update: [:renderer | self
renderSecondListOn: renderer ].

renderSecondListOn: html
       html select
                        id: 'listBID';
                        list: #('1' '2' '3' '4' '5' '6');
                        selected: numb

Cheers
Gerhard
