the page is re-rendered on each reload. So there's no reason why the
status should be shown "open" again.
Except your code keeps hold of stale information.
Furthermore Wicket pages are never cached by the browser (maybe this was
different in 2010?).
So we could discuss page versioning, but maybe we could first check what
problem you're actually trying to solve.

I am concerned that this sort of behavior could lead to error states.
I would feel better if there would not be any way to get back to the
old state, i.e. that the ?pageId in the url should be removed for
pages using AJAX.
I tried to achieve this in the following ways but failed:
Disable the versioning by calling the method/Page#//setVersioned(false):/
https://ci.apache.org/projects/wicket/guide/8.x/single.html#_turning_off_page_versioning
Providing a custom "MountedMapper" as show here and mentioned in the
corresponding conversation:
https://github.com/martin-g/single-page-instance
Setting cache control headers to force a page reload:

Is there any chance that the disabling of page versioning could become
a first-class feature?
Kind regards,
Jan
