[Seaside] How to change callback for html select on the fly

[Bob Arning]

I think this does what you were looking for. I got stymied for a while 
hitting return after changing the value in the text field. This caused a 
complete redraw and did not activate the updater callback. If I hit tab 
instead of return, things started working. FYI.

Cheers,
Bob

renderContentOnSqueakman1: html

     | fid mid saveText |

     fid _ html nextId.
     mid _ html nextId.
     html form
         id: fid;
         with: [
             (html textInput)
                 value: 'initial';
                 callback: [:v | saveText _ v];
                 onChange: ((html scriptaculous updater)
                         id: mid;
                         triggerForm: fid;
                         callback: [:r |
                                 self renderTheListWith: saveText 
asArray on: r
                     ]
                 ).
             html div
                 id: mid;
                 with: [
                     self renderTheListWith: #(30 50 60) on: html
                 ]
         ].

renderTheListWith: data on: html

     html text: 'Choose Amount'.
     html select
             callback: [:v | self amount: v];
             list: data.
