Emond Papegaaij commented on WICKET-6702:
-----------------------------------------
[~svenmeier] as you can see, I've pushed a change to swap the order of
serialization and async to make the serialization happen synchronously. I've
only made this change on Wicket 9, as the codebase in Wicket 8 is completely
different in this area. Unfortunately, I do not have a working testcase on
Wicket 8 to reproduce the issue and I lack the time to dive into this. What do
you think we should do with Wicket 8?
About the comment from Tobias, I can file a new ticket, but unfortunately, the
same applies: I don't have the time at the moment to pursue this. What do you
think? Is it even feasible to close the request while prior to serialization
(maybe even prior to detach)?

> Key: WICKET-6702
> URL: https://issues.apache.org/jira/browse/WICKET-6702
> Project: Wicket
> Issue Type: Bug
> Components: wicket-core
> Affects Versions: 8.5.0, 9.0.0
> Reporter: Sergei Tkachuk
> Priority: Major
> Attachments: QuickStart.zip
>
>
> Preconditions: Application uses AsynchronousPageStore (as it is by default).
> When there are several fast sequential Ajax calls to a component, then a
> component's LoadableDetachableModel gets attached and detached several times
> before real async serialization takes place. And at times the serialization
> is initiated when the model has been already attached once again by a
> subsequent Ajax call, and not detached yet as the request is still in
> progress. This causes NotDetachedModelChecker() to throw "Not detached model
> found!" exception
> Disabling async serialization fixes the problem.
> A test-case and a log attached.
