[ https://issues.jboss.org/browse/RF-12976?page=com.atlassian.jira.plugin.s... ] Lukáš Fryč commented on RF-12976: --------------------------------- The issue is in that {{TogglePanelTagHandler}} calls [{{addItemChangeListener}}|https://github.com/richfaces/richfaces5/blob/master/framework/src/main/java/org/richfaces/ui/toggle/TogglePanelTagHandler.java#L73] method for each build of a view. It adds {{FacesListener}} to the [{{AttachedObjectListerHolder}}|http://grepcode.com/file/repo1.maven.org/maven2/org.glassfish/javax.faces/2.1.19/javax/faces/component/UIComponentBase.java#892] in {{UIComponentBase}}. Since the bound UITabPanel is stored in a view scope, the list of listeners grows with each subsequent request for a same view. ---- This issue is larger and each of our change listeners should be checked for a same problem. -- This message is automatically generated by JIRA.
