Ernesto Reinaldo Barreiro commented on WICKET-6702: --------------------------------------------------- After checking our private issues I think we might have found the same problems in a page with a very aggressive timer. > AsynchronousPageStore with NotDetachedModelChecker - "Not detached model > found" exception on several fast sequential Ajax calls > ------------------------------------------------------------------------------------------------------------------------------- > > 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 > Fix For: 9.1.0 > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
