----------------------------------------
Summary: Combination of Trinidad with MyFaces Core and Spring
WebFlow doesn't function
Key: TRINIDAD-2537
URL: https://issues.apache.org/jira/browse/TRINIDAD-2537
Project: MyFaces Trinidad
Issue Type: Bug
Components: Facelets
Affects Versions: 2.1.0-core
Environment: MyFaces Core 2.1.17 (instead of Mojarra)
Trinidad 2.0.1
Spring WebFlow 2.4.2
Tomcat 7.0.35
Windows 7 64 bit
Java 8.0.45-64bit
Reporter: Volker Malzahn
When starting a webapp based on Trinidad and Spring WebFlow with MyFaces Core
as JSF implementation following exception occurrs:
java.lang.ClassNotFoundException:
com.sun.faces.component.CompositeComponentStackManager
java.net.URLClassLoader.findClass(URLClassLoader.java:381)
java.lang.ClassLoader.loadClass(ClassLoader.java:424)

org.springframework.webflow.engine.Flow.resume(Flow.java:537)
Reason:
org.springframework.faces.webflow.JsfRuntimeInformation.isMyFacesInUse()
returns false because of following bug in Trinidad:
org.apache.myfaces.trinidadinternal.context.FacesContextFactoryImpl extends
javax.faces.context.FacesContextFactory but FacesContextFactory.getWrapped()
isn't overwritten. So getWrapped() returns null which causes the loop in
org.springframework.faces.webflow.JsfRuntimeInformation.checkMyFacesContextFactory()
to terminate and to return false.
Solution: Add following method to
org.apache.myfaces.trinidadinternal.context.FacesContextFactoryImpl:
@Override
public FacesContextFactory getWrapped() {
return _factory;
}
