What I do is have the enclosed component trigger an event. That event returns a MultiZoneUpdate
object that I handle in the event callback and add the enclosed component to. I then return a
MultiZoneUpdate object containing both the ids and bodys of the two components to be updated from
the event handler in the enclosed component. looks like this:
parent component (update some navigation pane):
Object onUpdateNavigation()
{
if (request.isXHR())
return new MultiZoneUpdate("navigationZone", navigationZone.getBody());
return null;
}
enclosed component:
@CommitAfter
Object onSuccess()
{
session.saveOrUpdate(value);
ComponentEventCallback<Object> callback = new
ComponentEventCallback<Object>() {
public boolean handleResult(Object result)
{
update = (MultiZoneUpdate) result;
return false;
}
};
componentResources.triggerEvent("updateNavigation", null, callback);
if(request.isXHR())
return update.add(zoneId, componentResources.getComponent());
return null;
}

I have a component with a zone in it. Inside the zone is an embedded
component which also contains a zone. The main zone is a customer detail
page, while the inner component shows a list of contacts and has a link to
mark one as the primary contact. The customer details include the primary
contact name and phone number if one is selected.
I cannot find a way to get both the detail zone and the embedded contacts
zone to update when selecting a primary contact. I tried using multizone
updates, but the embedded component cannot update a zone it does not
contain.
How do I fire an event on a component from an embedded component?
