> We need to evaluate the AjaxRequestTarget to determine if a component has
> been directly added (as opposed to the component rendering because of a
> parent component being added). This is useful for applying markup wrapping
> through the use of behaviors. This is required because, on a ajax request -
> and if the component that has the markup wrapping behavior was added directly
> to the AjaxRequestTarget, the markup provided with the behavior will be
> duplicated. We currently have a workaround but it required the use of a
> custom AjaxRequestTarget:
> public class AjaxRequestTarget extends
> org.apache.wicket.ajax.AjaxRequestTarget {
> private Map<String, Boolean> addedComponents = new HashMap<String,
> Boolean>();
> public AjaxRequestTarget(Page page) {
> super(page);
> }
> @Override
> public void addComponent(Component component) {
> addedComponents.put(component.getMarkupId(), Boolean.TRUE);
> super.addComponent(component);
> }
> public boolean wasComponentAdded(Component component) {
> return (null != addedComponents.get(component.getMarkupId()));
> }
> }
> It would be nice if the Wicket AjaxRequestTarget had a method (the name of
> the method name doesn't really matter and is just for example purposes) like
> the following:
> public boolean wasComponentAdded(Component component) {
> return (null != markupIdToComponent.get(component.getMarkupId());
> }
