----------------------------------------

             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)
	sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
	java.lang.ClassLoader.loadClass(ClassLoader.java:357)
	org.springframework.faces.webflow.JsfViewFactory$MojarraProcessTreeHandler.handleBefore(JsfViewFactory.java:225)
	org.springframework.faces.webflow.JsfViewFactory.processTree(JsfViewFactory.java:166)
	org.springframework.faces.webflow.JsfViewFactory.getViewStateViewRoot(JsfViewFactory.java:138)
	org.springframework.faces.webflow.JsfViewFactory.getViewRoot(JsfViewFactory.java:102)
	org.springframework.faces.webflow.JsfViewFactory.getView(JsfViewFactory.java:86)
	org.springframework.webflow.engine.ViewState.resume(ViewState.java:192)
	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;
	}
