AjaxFormComponentUpdatingBehavior to enable/disable a component

2012-04-12 Thread dpmihai 
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?

Re: AjaxFormComponentUpdatingBehavior to enable/disable a component

Thanks a lot. I did not see it.

Also my first error in Wicket Ajax Debug was because I had some invisible
components in my ListItem. 
So after I checked also for visibility everything was ok.
