You're exactly right for my specific usecase. Consider this example.
I've got a Person class which contains an address property of type
Address. Now, Address is re-used in my domain model in a lot of
places (Vendor, Customer, etc.). So, everywhere we want to edit an
Address, we want it to use the same interface. So, I create an
AddressEditorPanel which to re-use on any form which contains an
Address object. So, now consider a page which is for editing a Person
object. I create a Form<Person> and on that I put an
AddressEditorPanel which will be used to edit the person's address
(new AddressEditorPanel("address") if using a CPM). Let's say the
AddressEditorPanel does some AJAX-based validation (for the zip code
perhaps). I want all my errors on that page to show up on the
FeedbackPanel located at the top of the page. If I have a validation
error on the zip code, I need to tell the AjaxRequestTarget that I
want the feedback panel updated via AJAX, but how do I do that? I
need a reference to the FeedbackPanel. Where do I get it? Well, I
either have it passed in to me or I look up my hierarchy and do it
that way. Using the auto-add feature (with a listener), it's handled
for me automagically!
