问题 I get a NullPointerException when navigating on a PrimeFaces menu item with ajax = true when JSF 2.3 websockets are present in the pages. Below is the exception: java.lang.NullPointerException at com.sun.faces.push.WebsocketFacesListener.processEvent(WebsocketFacesListener.java:100) at javax.faces.event.SystemEvent.processListener(SystemEvent.java:123) at javax.faces.event.ComponentSystemEvent.processListener(ComponentSystemEvent.java:110) at com.sun.faces.application.applicationimpl.Events

问题 This application has been working fine in TC7, Spring 3, and JSF 2.2 but I wanted to add the push capabilities of JSF 2.3 so I upgraded to TC 9.0.8, Spring 5.0.5, and JSF 2.3.0 After some simple initial problems due to the upgrades The app deploys fine and Spring Security works (I can login) but then I get this error: May 11, 2018 2:24:06 PM com.sun.faces.application.view.FaceletViewHandlingStrategy handleRenderException SEVERE: Error Rendering View[/index.xhtml] java.lang

问题 I cannot find out why the first ajax call causes the setter of my view parameter to be called again while every subsequent call does not call the setter again. I have the following simple view bean: package test; import java.io.Serializable; import javax.faces.view.ViewScoped; import javax.inject.Named; @Named @ViewScoped public class TestController implements Serializable { private static final long serialVersionUID = 1L; String param; public String getParam() { return param; } public void
