IllegalStateException when redirecting from system event in JSF managed bean ---------------------------------------------------------------------------- Key: WELD-1037 URL: https://issues.jboss.org/browse/WELD-1037 Project: Weld Issue Type: Bug Components: Web Tier integration (JSF, JSP, EL and Servlet) Affects Versions: 1.1.2.Final Environment: JBoss AS7 Reporter: Kristof Vanbecelaere I have a view with a system event like so <f:metadata> <f:event type="preRenderView" listener="#{fileUploadBean.checkAccessToken}" /> </f:metadata> the listener is just a faces managed bean and performs a redirect using FacesContext.getCurrentInstance().getExternalContext().redirect(...); This leads to an exception. When I disable Weld by removing the empty beans.xml file the redirect works fine. java.lang.IllegalStateException org.apache.catalina.connector.ResponseFacade.sendRedirect(ResponseFacade.java:436) javax.servlet.http.HttpServletResponseWrapper.sendRedirect(HttpServletResponseWrapper.java:170) org.jboss.weld.servlet.ConversationPropagationFilter$1.sendRedirect(ConversationPropagationFilter.java:90) com.sun.faces.context.ExternalContextImpl.redirect(ExternalContextImpl.java:576) org.dirtybxl.upload.FileUploadBean.redirectToAuthenticationEntrypoint(FileUploadBean.java:105) org.dirtybxl.upload.FileUploadBean.checkAccessToken(FileUploadBean.java:87) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) java.lang.reflect.Method.invoke(Method.java:597) org.apache.el.parser.AstValue.invoke(AstValue.java:196) org.apache.el.MethodExpressionImpl.invoke(MethodExpressionImpl.java:276) org.jboss.weld.util.el.ForwardingMethodExpression.invoke(ForwardingMethodExpression.java:43) org.jboss.weld.el.WeldMethodExpression.invoke(WeldMethodExpression.java:56) com.sun.faces.facelets.el.TagMethodExpression.invoke(TagMethodExpression.java:105) com.sun.faces.facelets.tag.jsf.core.DeclarativeSystemEventListener.processEvent(EventHandler.java:131) javax.faces.component.UIComponent$ComponentSystemEventListenerAdapter.processEvent(UIComponent.java:2508) javax.faces.event.SystemEvent.processListener(SystemEvent.java:106) com.sun.faces.application.ApplicationImpl.processListeners(ApplicationImpl.java:2129) com.sun.faces.application.ApplicationImpl.invokeComponentListenersFor(ApplicationImpl.java:2077) com.sun.faces.application.ApplicationImpl.publishEvent(ApplicationImpl.java:286) com.sun.faces.application.ApplicationImpl.publishEvent(ApplicationImpl.java:244) org.jboss.as.weld.webtier.jsf.ForwardingApplication.publishEvent(ForwardingApplication.java:293) com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:108) com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101) com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:139) javax.faces.webapp.FacesServlet.service(FacesServlet.java:594) org.primefaces.webapp.filter.FileUploadFilter.doFilter(FileUploadFilter.java:79) org.jboss.weld.servlet.ConversationPropagationFilter.doFilter(ConversationPropagationFilter.java:67) -- This message is automatically generated by JIRA.
