Description
While trying to deploy JSF2.2/CDI porltes on Liferay 6.2 on Wildfly (#938) a NPE is thrown in WeldInitialListener.requestInitialized method :
11:02:27,525 ERROR [default task-10][render_portlet_jsp:132] null java.lang.NullPointerException at org.jboss.weld.servlet.WeldInitialListener.requestInitialized(WeldInitialListener.java:144) at org.jboss.weld.servlet.WeldCrossContextFilter.doFilter(WeldCrossContextFilter.java:58) at com.liferay.portal.kernel.servlet.filters.invoker.InvokerFilterChain.processDoFilter(InvokerFilterChain.java:204) at com.liferay.portal.kernel.servlet.filters.invoker.InvokerFilterChain.doFilter(InvokerFilterChain.java:109) at com.liferay.cdi.portlet.bridge.CDICrossContextFilter.doFilter(CDICrossContextFilter.java:49) at com.liferay.portal.kernel.servlet.filters.invoker.InvokerFilterChain.processDoFilter(InvokerFilterChain.java:204) at com.liferay.portal.kernel.servlet.filters.invoker.InvokerFilterChain.doFilter(InvokerFilterChain.java:109) at com.liferay.portal.kernel.servlet.filters.invoker.InvokerFilter.doFilter(InvokerFilter.java:96) at io.undertow.servlet.core.ManagedFilter.doFilter(ManagedFilter.java:56)at io.undertow.servlet.handlers.FilterHandler$FilterChainImpl.doFilter(FilterHandler.java:132) at io.undertow.servlet.handlers.FilterHandler.handleRequest(FilterHandler.java:85) at io.undertow.servlet.handlers.security.ServletSecurityRoleHandler.handleRequest(ServletSecurityRoleHandler.java:61) at io.undertow.servlet.handlers.ServletDispatchingHandler.handleRequest(ServletDispatchingHandler.java:36) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:25) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:25) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:25) at io.undertow.servlet.handlers.ServletInitialHandler.dispatchRequest(ServletInitialHandler.java:229) at io.undertow.servlet.handlers.ServletInitialHandler.dispatchToServlet(ServletInitialHandler.java:178) at io.undertow.servlet.spec.RequestDispatcherImpl.include(RequestDispatcherImpl.java:275) at com.liferay.portlet.InvokerPortletImpl.invoke(InvokerPortletImpl.java:604)
Tracking down 2.1.2.Final source code I identified that WeldCrossContextFilter creates a new instance of WeldInitialListener which has no constructors or initialization mechanism so beanManager and lifeclyce fields are null. After fixing that, another NPE is thrown because the SessionHandler hard-codes not to create the session if is still not crated. A portlet session must be created within the first render attempt.
I created a fix for the two issues that allows the Liferay example portlet (https://github.com/liferay/liferay-faces/tree/master/demos/bridge/jsf2-cdi-portlet) render. https://github.com/parsek-doo/weld-core/compare/weld:2.1...2.1.2-portlet?expand=1
