> -------------------------------------------------------------------------------------------------------------------------------

> 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
> Reporter: Sergei Tkachuk
> Priority: Major
> Attachments: SerializationProblemPage.html,
> SerializationProblemPage.java, SerializationProblemPage.log,
> TestSerializationProblemPage.java
>
>
> 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.
