Hi, The form components aren't updated because form processing for AjaxSubmitLink is set to false. See the javadoc for AjaxSubmitLink#setDefaultFormProcessing.
BTW, when using ListView for rendering form components consider reading WARNING section in javadoc for ListView class. ----- Исходное сообщение ----- От: "Sebastian80" <[email protected]> Кому: [email protected] Отправленные: Суббота, 12 Ноябрь 2011 г 17:46:51 Тема: Model isn't updated on AJAX submit link invocation Hi there, I'm trying to implement an AJAXfied Wicket list view. On my research I stumbled upon the code on http://www.oktech.hu/kb/adding-and-removing-rows-wicket-listview-via-ajax and modified it a bit. The model is not updated properly. So whenever a value is entered in a text field, it is forgotten if the AJAX submit link is invoked (the text field is empty again). Why does this happen? I don't see any issue with this code. Wicket version is 1.5.2. Here is the Java code: // Initialization of form ... // List all rows ArrayList<String> rows = new ArrayList<String>(2); rows.add(new String()); rows.add(new String()); final ListView<String> lv = new ListView<String>("rows", rows) { @Override protected void populateItem(ListItem<String> item) { int index = item.getIndex() + 1; item.add(new Label("index", index + ".")); TextField<String> text = new TextField<String>("text", item.getModel()); item.add(text); } }; rowPanel.add(lv); AjaxSubmitLink addLink = new AjaxSubmitLink("addRow", form) { @Override protected void onError(AjaxRequestTarget target, Form<?> form) { if (target != null) target.add(rowPanel); } @Override protected void onSubmit(AjaxRequestTarget target, Form<?> form) { lv.getModelObject().add(new String()); if (target != null) target.add(rowPanel); } }; addLink.setDefaultFormProcessing(false); rowPanel.add(addLink); ... And the associated mark up: <div wicket:id="rowPanel"> 1. <input type="text" wicket:id="text"/> # Add row </div> Has someone any idea on this issue? I'm completely stuck on this issue. Thanks in advance.
