I'm using the select component due to realizing a dynamic optgroup and option list. It works rather fine but my problem is to get the selected value. I tried to use an ajax behavior (AjaxComponentUpdatingBehavior, OnChangeBehavior) but the onUpdate methode is never called --> doesn't work!
Maybe there is a solution for my problem!? What I'm doing wrong? My code: Select select = new Select(selectId); select.add(new ListView("optGroups", myList) { @Override protected void populateItem(ListItem item) { MyBean myBean = (MyBean) item.getModelObject(); item.add(new OptGroup("optGroup", myBean.getName(), myBean.getList())); } }); add(select); class OptGroup extends SelectOption { String label; List<MyBean2> list; public OptGroup(String id, String label, List<MyBean2> list) { super(id); this.label = label; this.list = list; init(); } @SuppressWarnings("unchecked") private void init() { this.add(new ListView("grpOptions", list) { @Override protected void populateItem(ListItem item) { MyBean2 myBean2 = (MyBean2) item.getModelObject(); item.add(new CustomSelectOption("grpOption", myBean2.getName())); } }); } protected void onComponentTag(final ComponentTag tag) { checkComponentTag(tag, "optgroup"); Select select = (Select) findParent(Select.class); if (select == null) { throw new WicketRuntimeException( "OptGroup component [" + getPath() + "] cannot find its parent Select. All OptGroup components must be a child of or below in the hierarchy of a Select component."); } tag.put("label", label); } } public class CustomSelectOption extends SelectOption { @SuppressWarnings("unchecked") public CustomSelectOption(String id, String displayValue) { super(id, new Model(displayValue)); } protected void onComponentTagBody(final MarkupStream markupStream, final ComponentTag openTag) { replaceComponentTagBody(markupStream, openTag, getDefaultModelObjectAsString()); } } I tried this, but it doesn't work: select.add(new AjaxFormComponentUpdatingBehavior("onchange") { protected void onUpdate(AjaxRequestTarget target) { System.out.println("Update ajax"); // @todo updating model } }); -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Problem-get-selected-value-using-dynamic-select-with-optgroup-tp3318883p3318883.html Sent from the Users forum mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
