Major Description
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)
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());
}
