Process Train Only goes Forward

Question

I am trying to implement the process train sample from the programming guide. I have it all wired up and things show up correctly, but the process will only go foward, can anybody see something I missed?
From my Faces File

Nothing proprietary, but I made up a quick example derived from mine that has simplified names:

<navigation-case>
<from-outcome>C</from-outcome>
<to-view-id>/C.jspx</to-view-id>
</navigation-case>
</navigation-rule>
</faces-config>
And one of the jspx files, C.jspx, just change the panelHeader for display:
<?xml version="1.0" encoding="iso-8859-1" standalone="yes" ?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="1.2"
  xmlns:f="http://java.sun.com/jsf/core"
  xmlns:af="http://xmlns.oracle.com/adf/faces"
  >
  <jsp:directive.page contentType="text/html;charset=utf-8"/>
  <f:view>
    <af:document>
      <af:form>
        <af:processTrain var="foo"
          value="#{NavigationMenuModel}">
          <f:facet name="nodeStamp">
            <af:commandMenuItem text="#{foo.label}"
              action="#{foo.getOutcome}"
              immediate="#{NavigationMenuModel.immediate}"
              readOnly="#{NavigationMenuModel.readOnly}"
              />
          </f:facet>
        </af:processTrain>
        <af:objectSpacer height="50"/>
        <af:panelHeader text="C"/>
      </af:form>
    </af:document>
  </f:view>
</jsp:root>MenuItem is copied verbatim from classes/oracle/adfdemo/view/faces/menu/DemoMenuItem.java and I just have it stored in my webapp at WEB-INF/classes/MenuItem.class. Nothing fancy, but I can go back and forth. I have this example working here, but like I said previously, I'm kind of cargo culting here. For me, processTrain is one of the more odd components probably because most of the component wiring happens in xml.
