Nick Pratt commented on WICKET-5082:
------------------------------------
So normal page rendering uses a ChildFirstHeaderRenderStrategy (since 1.5), but
the Ajax header writing doesnt seem to follow that strategy and writes parent
first then children (AbstractAjaxResponse.writeHeaderContribution() )is there a
reason we couldnt render both normal and ajax updates with the same order?
> Ajax update renders parent/child JS in different order than initial Page
> render

> Key: WICKET-5082
> URL: https://issues.apache.org/jira/browse/WICKET-5082
> Project: Wicket
> Issue Type: Bug
> Affects Versions: 6.6.0
> Reporter: Nick Pratt
> Attachments: quickstart.tar.gz
>
>
> See attached quickstart. On initial page load, the child Javascripts are
> rendered and executed first, followed by the parent's JS - in this case a
> Datatables.net JS. Everything works fine.
> However, if you click on a link in the DefaultDataTable, we trigger a DDT
> refresh via Ajax, and then you can see that the parent's JS is executed
> first, before the child JS - this causes a problem since the parent JS
> modifies the visible rows in the table and Wicket can no longer find some of
> the child rows.
> I expected the order of JS contributions to be the same for initial page
> render and any Ajax updates.
