Re: AjaxFallBackLink updating a listview in a listview (blog entry)
Hi Sven, I am trying to implement your changes, but am not sure what you
mean:
I have 3 panels in a page
(QuestionCompletePage
-QuestionCompletePanel-CompletableQuestionPanel-QuestionNavigationPanel).
However, QuestionNavigationPanel, that contains my AjaxLink, belongs to two
execution paths (it is used in QuestionCompletePage and QuestionEditPage).
So I create an interface IRefreshable and have QuestionCompletePanel
implement it (because it contains the container that I want to refresh).
public interface IRefreshable {
public ListComponent getRefreshables();
}
Normally, I would then either have to pass a reference to this panel or
otherwise, navigate down from getPage() to get to the panel. This seems to
be just as much work as including the container for refreshing in the
constructor calls.
Any tips appreciated.

IMHO passing the container into EditableQuestionPanel isn't a good idea -
why should it know anything about its parent? Instead I'd add a hook method
into EditableQuestionPanel so that it can notify about changes. The
containing QuestionEditPanel can then do whatever it needs to update itself
on an Ajax request.

I'm afraid forcing the reader to enter credentials isn't going to increase your comment count. Nevertheless here are some suggestions: A) Use PropertyListView and you won't have to twiddle with the item's model. B) IMHO passing the container into EditableQuestionPanel isn't a good idea - why should it know anything about its parent? Instead I'd add a hook method into EditableQuestionPanel so that it can notify about changes. The containing QuestionEditPanel can then do whatever it needs to update itself on an Ajax request. C) Why is QuestionNavigationPanel concerned with the model object of one of its ancestors? QuestionEditPanel should use a LoadableDetachableModel to always work on up-to-date data. When notified of changes (see hook method above) it can detach its model explicitly so the data is fetched again from your QuestionProcessor.
