[Seaside] Nested Multi-Select-List.

[Dario Trussardi]

<That's not the way Seaside works. You cannot instantiate tags and
<reuse them multiple times in different rendering contexts.
<
<So to make your example works you need to split you code into multiple
<rendering methods. This is good practice anyway, it is painful trying
<to understand the code when written in one huge method like this. So
<instead of
<
<    scnCnt:=  html select id: idScnCnt;
<          ....
<
<you create a method that renders this part and call it from your
<callback blocks.

Thank Lukas.


The new metod now is:

  frsCnt:=  html select id: ( idFrstCnt:= html nextId);
                size: 4;
                beMultiple; 
      list: (1 to: 100);
                selected: mutliSelectList;
       callback: [ :value | mutliSelectList := value ];  
                                
                     onChange:( html updater
                     id:  idScnCnt; 
                     triggerForm: fid;
                     callback: [ :r |   self creaScnCnt: html.  ]).
      
     rfrScnCnt:=  html span class: 'dario' ;  id: idScnCnt; with:'PLUTO'.  
   



and the creaScnCnt is

creaScnCnt: html

 | mid1 |
 
mid1:= html nextId.
 scnCnt := html select id: ( html nextId) ;
                size: 4;
                beMultiple; 
                list: self listaScn;
                 selected: scnMultiSelectList; 
                callback: [ :value | scnMultiSelectList := value ];
                onChange: (html updater
                     id: idTrzCnt ;
                     triggerForm: fid;
                     callback: [ :r | self creaTrzCnt: html. )].
 
   rfrTrzCnt:=  html span class: 'dario' ;  id: idTrzCnt; with:'Archimede'.



In this case all functions but when i select the Toggle Halos link the Slave Multi-Select-List is lose.

Is this correct operation ?

Cheers,

Dario
