yi gong updated Bug WELD-1247
Change By: yi gong (06/Nov/12 3:18 AM)
Original Estimate: 2 hours
Remaining Estimate: 2 hours
Environment: Tomcat 7 and Mojarra 2.1.3
Description: The equals() implementation is incorrect
 @Override
    public boolean equals(Object obj) {
        return this == obj || delegate().equals(obj);
    }

if the obj is a WeldMethodExpression, it returns false which cause add duplicated Listener
Please see Mojarra
javax.faces.componentUIComponentBase
    public void subscribeToEvent(Class<? extends SystemEvent> eventClass,
                                 ComponentSystemEventListener componentListener) {
...
        if (!listenersForEventClass.contains(facesLifecycleListener)) {
            listenersForEventClass.add(facesLifecycleListener);
        }

    }
Complexity: Low
Steps to Reproduce: Please use the project I upload. After package and deploy, launch the url http://localhost:8080/testjsf/faces/index.xhtml. You can see the Bean.Action is executed twice.
