I think the issue here is that he'd like one deeply nested component, let's
call it Z, to be refreshed when another deeply nested component, let's call it
N, that doesn't know about Z, is refreshed.
One way is to bubble up an event from N until it reaches a common parent, C,
which in this example is the parent of the layout. C then calls
component.doChangeOfNotifications(), which calls
componentA.doChangeOfNotifications(), which calls ... etc. .. which calls
Z.doChangeOfNotifications(). Messy, with lots of components needing new method
doChangeOfNotifications. You can see something like this in:
http://jumpstart.doublenegative.com.au/jumpstart7/together/ajaxcomponentscrud/persons
where Persons, which is the page, calls list.doChangeOfSelectedPerson() in
response to several bubbled-up events.
Ideally, a synchronous pub-sub server-side could solve it. N would publish and
Z would subscribe. Z would use AjaxResponseRenderer to add its zone to the
render list. Unfortunately, I don't know of such a mechanism.
Any other suggestions?
