I am working on a project using Spring Webflow and JSF. I am trying to accomplish something similar to the booking-faces example of Spring Webflow https://github.com/SpringSource/spring-webflow-samples/tree/master/booking-faces. I get the following error while trying to execute a web-flow.

I checked the answer from the stackoverflow post: java.lang.ClassNotFoundException: org.apache.myfaces.webapp.StartupServletContextListener . However I am using Maven and don't have a /WEB-INF/lib directory. I have JSF dependencies on my classpath through Maven dependencies. Not sure, what's going on. Thanks
MyFaces repackaged StateCacheUtils in version 2.1.10. So spring-webflow will not work with myfaces 2.1.10 or higher.
I created an issue in jira for this. Maybe it will be fixed in a further version.
Meanwhile there is a very very VERY ugly workaround for this problem:
Create a class org.apache.myfaces.rederkit.StateCacheUtils in your own project and let it inherit from the new location unsing the following code:
package org.apache.myfaces.renderkit;
public class StateCacheUtils extends org.apache.myfaces.application.viewstate.StateCacheUtils {
}
