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

Hello,

Gerhard thank you for your answer!

I succeed in re-rendering ListB after selecting something new in ListA with >>renderSecondListOn:.
So, this works now.

But the second problem still remains: after changing the code from "html scriptaculous updater" to the prototype version "html prototype evaluator", the callback (self numb: value) does not fire anymore.
I need the callback for saving the selected enty in an instance variable "numb".

How can I save the selected list entry in the inst var?

Greetings
Sabine


renderListAOn: html
    html
        form: [
            html select
                id: 'listAID';
                list: #('1' '2' '3' '4' '5' '6');
                selected: numb;
                callback: [ :value |
                            'fires' inspect.
                            self numb: value ];
                onChange:
                        (html prototype evaluator
                                callback: [ :script |

                                                id: 'formB';
                                                update: [ :renderer | self renderSecondListOn: renderer ] ];

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
