New attach->beforeRender refactor breaks ajax updating of list views
--------------------------------------------------------------------
Key: WICKET-558
URL: https://issues.apache.org/jira/browse/WICKET-558
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.3
Reporter: Jonathan Locke
Assigned To: Johan Compagner
Priority: Blocker
Because components are created in onBeforeRender in list views (it calls
populateItem then), it is necessary for AJAX renderings now to call
beforeRender on every component to be updated before proceeding with the
render. Since the current code does not do this, you get a NPE when rendering
happens since the item was never populated.
It looks like AjaxRequestTarget.respondComponent should call before render on
the component tree (similar to how it does in Page) just before it's about to
render. But I'm unsure if this is the right place to make the change.
Johan can you look at this since you were doing this refactor and probably know
all the details?
