Thank you, Igor, for getting back to me so quickly. Actually, thank you for answering at all.
I thought of the onclick handler, but the AjaxFallbackButton doesn't have an onClick() function. It does have a getOnClickScript() which I can override, but I believe the timing will be off. I think it will fire before the form is submitted. Hold on, I think I get what you're saying: write some JavaScript AJAX for the onclick script that will call whatever routines I need to create the user and then update the ListChoice's model. I don't need to do anything with the onSubmit() overload. Is that what you're saying? I will try it. I think it's a good idea. An interesting aspect of this solution is that I don't think I even need a form. I think the validation of control inputs would happen after the onclick handler returns. I think this is a strictly roll-your-own solution. Have I got it right? ________________________________________ From: Igor Vaynberg [EMAIL PROTECTED] Sent: Thursday, October 02, 2008 4:42 PM To: users@wicket.apache.org Subject: Re: How to update ListChoice after form submission? inside the onclick of your ajaxfallbackbutton you have to add the listchoice to the target so wicket rerenders it -igor On Thu, Oct 2, 2008 at 12:49 PM, Seven Corners <[EMAIL PROTECTED]> wrote: > > I have a page with a ListChoice of user names that is populated with a call > to our server (loadUserNames()).
