问题 I have added a PhaseListener to faces-config.xml : <lifecycle> <phase-listener>com.project.NotificationListener</phase-listener> </lifecycle> The class seems to be otherwise correct as it is pretty simple. public class NotificationListener implements PhaseListener { @Inject private MyCDIStuff stuff; @Override public PhaseId getPhaseId() { return PhaseId.RENDER_RESPONSE; } @Override public void beforePhase(PhaseEvent event) { this.stuff.doStuff(); } } The 'beforePhase' method gets called

问题 In my JSF2 application I have a phaselistener that needs to be executed before RENDER_RESPONSE but after JSF has built the viewroot. First, what I did is register my PhaseListener in faces-config. The listener then gets called, but when I perform the beforePhase, getViewRoot().getChildren() is still empty. Secondly, I found how to do this by adding the following on my xhtml pages: <f:phaseListener type="be.application.PolicyController" /> This works fine, but adding this to each of my pages
