I tested this idea by adding the code below to my web application
object. Problem was though,
that when viewing the variables in debugger, the enclosure object didn't
seem to be included in
the tree of the parent objects. It was as if the enclosure was invisible to
them. Perhaps because
Enclosure is a transparent resolver?
object tree in my application:
- page
- enclosure
- div (the parent of this was shown to be page, not the enclosure)
Code:
//-----------------------------
@Override public AjaxRequestTarget newAjaxRequestTarget(Page page) {
AjaxRequestTarget target = super.newAjaxRequestTarget(page);
target.addListener(new AjaxRequestTarget.IListener() { public void
onBeforeRespond(Map<String, Component> map, AjaxRequestTarget target) {
for(Component component : map.values()) { Enclosure parentEnclosure =
component.findParent(Enclosure.class); if (parentEnclosure != null) {
Enclosure topParent = new Enclosure("DUMMY", "DUMMY"); while (topParent !=
null) { topParent = parentEnclosure.findParent(Enclosure.class); if
(topParent != null) { parentEnclosure = topParent; } }
target.addComponent(parentEnclosure); } } } public void
onAfterRespond(Map<String, Component> map, IJavascriptResponse response) {}
}); return target; };
//-----------------------
