Thanks for your reply. I have some follow up questions to your respond: -1. Do you mean ListChoice.onSelectionChange is not invoked instead of ListChoice.onchange which is on client side?
ListChoice.onSelectionChange is not an ajax thing. And when you have both specified i think the ajaxbehavour will just override the onChange code that is inserted for the onSelectionChange event. 2. What and when do I use getCallbackUrl()? you don't use it. Is is just what gets generated for you that is inserted in the onchange of your select component in the html. 3. Am I right to presume the implementation in
AjaxFormComponentUpdatingBehavior.onUpdate(...) is to populate palette on client side? Why does your implementation keep adding components to target? My assumption is for target is "add the component you are referring to target"
onUpdate() == onSelectionChange but then as an ajax call. (both code are ofcourse server side..) addTarget is saying all those components must be rerendered. When the ajax request ends. johan
