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?
