SeasideAsync and scriptaculos

Hi,

i use seasideAsync liveCallback to intercept the change ( at character level ) in one textInput and dinamic update an list based on it value.

html textInput

value: field
callback:[ :v| field := v].

liveCallback:[:text :h| field:= text.

h div: 'idToUpdate' with: queryMethodBasedOn_Field: h].

Now i port my code into Gemstone, and i think to use only scriptacolous for do it.

I think it's not possible use together ( SeasideAsync and scriptaculos) in the same render code.

And i'm interested to conform, standarize the code.

What's the right method to do it ?

I tested :

html textInput
  id: (inputId := html nextId);
  exampleText: 'testo iniziale';
  callback: [ :value | self field: value ];

onEnter: ( html updater id: 'idToUpdate' ;
       callback:[ :h| self queryMethodBasedOn_Field: h ]).

html div id:'idToUpdate' ; with:[ self queryMethodBasedOn_Field: html].

With this code i d'ont intercept the character change, but only at Enter level and the field is'not update.

How i can intercept the change at character level, in the textInput and update the relative field?

And after update the list ?

Any pointers would be greatly appreciated!

Thanks!

Dario

You need to trigger the callback of the textInput. So your updater
should look like:

html updater
id: 'idToUpdate';
triggerFormElement: inputId;
callback: ...

Scriptaculous gives you a lot of freedom, but you have to take care of
a few more things to get that freedom ...
