Hello, guys, I encounter a strange error in my wicket logs. I don't have any idea what the reason may be. Would you give some hints? I have a simple WebApplication subclass with nothing special in it.
Thank you! Here's the stacktrace 20-09-2011 16:46:44,875 ERROR org.apache.wicket.request.cycle.RequestCycleListenerCollection$3.notify:105 - Error detaching request cycle listener: org.apache.wicket.Application$2@b45ad3d java.lang.IllegalArgumentException: Argument 'data' may not be null. at org.apache.wicket.util.lang.Args.notNull(Args.java:39) at org.apache.wicket.pageStore.AsynchronousDataStore$Entry.<init>(AsynchronousDataStore.java:271) at org.apache.wicket.pageStore.AsynchronousDataStore.storeData(AsynchronousDataStore.java:215) at org.apache.wicket.pageStore.DefaultPageStore.storePageData(DefaultPageStore.java:115) at org.apache.wicket.pageStore.DefaultPageStore.storePage(DefaultPageStore.java:144) at org.apache.wicket.page.PageStoreManager$PersistentRequestAdapter.storeTouchedPages(PageStoreManager.java:377) at org.apache.wicket.page.RequestAdapter.commitRequest(RequestAdapter.java:171) at org.apache.wicket.page.AbstractPageManager.commitRequest(AbstractPageManager.java:94) at org.apache.wicket.page.PageManagerDecorator.commitRequest(PageManagerDecorator.java:68) at org.apache.wicket.page.PageAccessSynchronizer$2.commitRequest(PageAccessSynchronizer.java:213) at org.apache.wicket.Application$2.onDetach(Application.java:1552) at org.apache.wicket.request.cycle.RequestCycleListenerCollection$3.notify(RequestCycleListenerCollection.java:101) at org.apache.wicket.request.cycle.RequestCycleListenerCollection$3.notify(RequestCycleListenerCollection.java:97) at org.apache.wicket.util.listener.ListenerCollection.reversedNotify(ListenerCollection.java:121) at org.apache.wicket.util.listener.ListenerCollection.reversedNotify(ListenerCollection.java:112) at org.apache.wicket.request.cycle.RequestCycleListenerCollection.onDetach(RequestCycleListenerCollection.java:95) at org.apache.wicket.request.cycle.RequestCycle.onDetach(RequestCycle.java:542) at org.apache.wicket.request.cycle.RequestCycle.detach(RequestCycle.java:481) at org.apache.wicket.request.cycle.RequestCycle.processRequestAndDetach(RequestCycle.java:257) at org.apache.wicket.protocol.http.WicketFilter.processRequest(WicketFilter.java:162) at org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:218) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:224) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:185) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:472) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:151) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:100) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:929) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:405) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:269) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:515) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:302) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662)
