Undertow breaks some JSF apps ----------------------------- Key: WFLY-1266 URL: https://issues.jboss.org/browse/WFLY-1266 Project: WildFly Issue Type: Bug Components: JSF Affects Versions: 8.0.0.Alpha1 Reporter: Stan Silvert Assignee: Stuart Douglas Priority: Critical Fix For: 8.0.0.Alpha1 Attachments: InjectionTest.zip Undertow breaks some JSF apps. I haven't narrowed the problem down yet but I want to go ahead and post this JIRA because it is a blocker for AS8. I'm attaching a small JSF project that demonstrates the problem. When you run the WAR with -c standalone-jbossweb.xml it works fine. With Undertow it breaks. You are unable to navigate based on the return value of a MethodExpression. Also, you get this warning: {noformat} 12:17:30,572 WARNING [javax.enterprise.resource.webcontainer.jsf.context] (default task-1) JSF1091: No mime type could be found for file /index.xhtml. To resolve this, add a mime-type mapping to the applications web.xml. {noformat}
