Sven, I have an additional situation where I am getting an internal error.
Could you help me in figuring out the problem?
Panel A senses the selection of an item from a user and adds the „sortable“ as
container to the ajax target.
In addition, Panel B should be added to the ajax target, using Wicket events.
The internal error is thrown when using Wicket events to add the additional
panel. Without the event, just calling #target.add(sortable) it works.
Panel A
*************
@Override
public void onSelect(AjaxRequestTarget target, List<String> items) {
sortable.onRemove(target, items.get(0));
target.add(sortable);
send(getPage(), Broadcast.BREADTH, new DeleteItem(target));
}
Panel B
*************
public class PoiListPanel extends Panel {
@Override
public void onEvent(IEvent<?> event) {
super.onEvent(event);
if (event.getPayload() instanceof DeleteItem) {
DeleteItem update = (DeleteItem) event.getPayload();
update.getTarget().add(this);
}
}
