Hi. I have a set of components C (anything you want Label, DateField, TextField, DropDownChoice ...) and another ChechBox inside a ListItem. I want to use the checkbox for enabling / disabling of all components C (when checkbox is selected I want to disable all C components):
final CheckBox dynamicChkBox = new CheckBox("dynamicChkBox", dynamicModel); dynamicChkBox.add(new AjaxFormComponentUpdatingBehavior("onchange") { protected void onUpdate(AjaxRequestTarget target) { Iterator it = item.iterator(); // item is my ListItem while (it.hasNext()) { Component component = (Component) it.next(); component.setEnabled(!(Boolean) dynamicModel.getObject()); if ((target != null) && !component.getId().startsWith("dynamic")) { target.add(component); } } } }); Initially dynamic check box is not selected. I select the checkbox and my set of components C becomes disabled as desired, but then if I deselect the chechbox I get an error: org.apache.wicket.request.handler.ListenerInvocationNotAllowedException: Behavior rejected interface invocation. Component: [CheckBox [Component id = dynamicChkBox]] Behavior: com.asf.nextserver.web.report.NextRuntimePanel$1 {event='onchange'} Listener: [RequestListenerInterface name=IBehaviorListener, method=public abstract void org.apache.wicket.behavior.IBehaviorListener.onRequest()] at org.apache.wicket.RequestListenerInterface.invoke(RequestListenerInterface.java:237) ..... I noticed that when I first select the checkbox even if the components are disabled Wicket Ajax Debug shows an error like : ERROR: Wicket.Ajax.Call.processComponent: Component with id [[txtTime145]] was not found while trying to perform markup update. Make sure you called component.setOutputMarkupId(true) on the component whose markup you are trying to update. I do not know why, because I put setOutputMarkupId(true) on all my components C. Is there somtehing I can do? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/AjaxFormComponentUpdatingBehavior-to-enable-disable-a-component-tp4551288p4551288.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
