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?
