Thank you, Igor. That did work; adding the ListChoice as a target component does get the AJAX to update properly. I am grateful for your help.
I had been trying to do it without AJAX, for the sake of browsers that don't allow JavaScript. Now, let me understand why it didn't work without AJAX. I thought that since the page after the submit was a copy of the original page, that we would do a round trip on submission. I thought we'd hit the constructor again and a trace shows we don't. I had thought the new page would load up whatever was in the models, and if I changed the model content before the submit was over, the new data should show up. Since it didn't, does this mean that the new page uses what's in the HTML rather than what's in the model? Or does it mean that even in a non-AJAX page, only the controls you add as onSubmit targets get updated with the model contents? igor.vaynberg wrote: > > it doesnt have an onclick() but it does have an onsubmit(). > > i suggest you take a look at how ajax examples work in our examples > project. if you want to repaint some part of the screen when you press > an ajax button you have to add that part to the ajax request target > using target.addcomponent() - that is how you tell wicket what to > repaint... > > -igor > > On Fri, Oct 3, 2008 at 5:52 AM, Shelah Horvitz > <[EMAIL PROTECTED]> wrote: >> Thank you, Igor, for getting back to me so quickly.
