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?
2. What and when do I use getCallbackUrl()? 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" Thanks Nino Wael wrote: > > With Listchoiec are no longer invoked, I meant listchoice.onchange. > > > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Nino Wael > Sent: 8. december 2006 12:51 > To: [email protected] > Subject: Re: [Wicket-user] Help with AjaxFormComponentUpdatingBehavior > > As you write ListChoice are no longer invoked.
