  • Hi, when loading serialized sessions and initializing it with didAcitivate the following stack-trace occurs: {code:java} java.util.ConcurrentModificationException at java.util.LinkedList$ListItr.checkForComodification(LinkedList.java:966) at java.util.LinkedList$ListItr.next(LinkedList.java:888) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2915) at org.zkoss.zul.Combobox.sessionDidActivate(Combobox.java:1060) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zul.Listbox.sessionDidActivate(Listbox.java:3269) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.AbstractComponent.sessionDidActivate(AbstractComponent.java:2921) at org.zkoss.zk.ui.impl.PageImpl.sessionDidActivate(PageImpl.java:1130) at org.zkoss.zk.ui.impl.DesktopImpl.sessDidActivate(DesktopImpl.java:1076) at org.zkoss.zk.ui.impl.DesktopImpl.sessionDidActivate(DesktopImpl.java:1021) at org.zkoss.zk.ui.impl.SimpleDesktopCache.sessionDidActivate(SimpleDesktopCache.java:203) at org.zkoss.zk.ui.impl.SessionDesktopCacheProvider.sessionDidActivate(SessionDesktopCacheProvider.java:77) at org.zkoss.zk.ui.impl.AbstractWebApp.sessionDidActivate(AbstractWebApp.java:366) at org.zkoss.zk.ui.http.SimpleSession$2.didActivate(SimpleSession.java:520) at org.zkoss.zk.ui.http.WebManager.addActivationListener(WebManager.java:367) at org.zkoss.zk.ui.http.SimpleSession.sessionDidActivate(SimpleSession.java:515) at org.zkoss.zk.ui.http.SerializableSession.sessionDidActivate(SerializableSession.java:65) {code} This also depends on the session's desktops and views and does not occur any times. Will post a pull request on github for this.
