I have reworked this a bit but am still having problems getting any methods called from jPdl. As far as I can tell, I am closely following the DVD Seam example

Here is my pageflow.jdpl.xml

<pageflow-definition

 xsi:schemaLocation= "http://jboss.com/products/seam/pageflow http://jboss.com/products/seam/pageflow-1.2.xsd"
 name="serviceRequestCreation">

 <start-state name="start">
 <transition to="requestSearch"/>
 </start-state>
 <page name="requestSearch" view-id="/AddressLookup.xhtml">
 <redirect/>
 <transition name="viewRequests" to="requestListing">
 <action expression="#{requestEntry.viewRequests}"/>
 </transition>
 </page>
 <page name="requestListing" view-id="/AddressRequestListing.xhtml">
 <redirect/>
 <end-conversation/>
 </page>
</pageflow-definition>

@Stateful
@Name("requestEntry")
public class RequestEntryAction implements com.stlouiscity.csb.ejb.action.RequestEntry {

 @PersistenceContext(unitName="CSB_Oracle", type=EXTENDED)
 private EntityManager em;

 @In(create=true)
 private Address address;

 @In(create=true, required=false)
 private AddressLookup addressLookup;

 @DataModel("addresses")
 private List<ParcelAddress> addresses;

 @DataModelSelection(value="addresses")

 private ParcelAddress selectedAddress;

 @DataModel("requests")
 private List<ServiceRequest> requests;

 @DataModelSelection(value="requests")
 private ServiceRequest selectedRequest;

 /**

 */
 public RequestEntryAction() {
 }

 @Begin(join=true)
 public void findAddresses() {

 if (address.getStreetName() != null) {
 System.out.println("Address Is NOT NULL");
 //Find ParcelAddress
 Query q = em.createQuery("Select a From ParcelAddress a Where" +
 " (a.structureAddress.nlc.streetDirection = :streetDirection OR :streetDirection IS NULL) AND" +

 q.setParameter("houseNumber",address.getHouseNumber());
 q.setParameter("streetDirection",address.getStreetDirection());
 q.setParameter("street",address.getStreetName().toLowerCase() + "%");

 addresses = q.getResultList();
 } else {
 System.out.println("Address IS NULL");
 }
 }

 @Begin(nested=true, pageflow="serviceRequestCreation")
 public void viewRequests() {
 System.out.println("**********Started PageFlow*************");
 }

 @End
 public void findRequests(ParcelAddress address) {
 System.out.println("**********Entered findRequests*************");
 System.out.println("**********Selected Address: " + address.toString());
 Query q = em.createQuery("Select s From ServiceRequest s Where" +
 " s.parcelAddress.parcelAddressPK.houseNumber = :houseNumber AND" +
 " s.parcelAddress.parcelAddressPK.houseSuffix = :houseSuffix AND" +
 " s.parcelAddress.parcelAddressPK.nlc = :nlc AND" +
 " s.parcelAddress.parcelAddressPK.cityBlock = :cityBlock AND" +

 q.setParameter("houseNumber", address.getParcelAddressPK().getHouseNumber());
 q.setParameter("houseSuffix", address.getParcelAddressPK().getHouseSuffix());
 q.setParameter("nlc", address.getParcelAddressPK().getNlc());
 q.setParameter("cityBlock", address.getParcelAddressPK().getCityBlock());
 q.setParameter("parcelNumber", address.getParcelAddressPK().getParcelNumber());
 requests = q.getResultList();
 }

 @Remove @Destroy
 public void destroy() {

 }

I got it working. I was never actually beginning the pageflow. I am now calling the viewRequests method of the bean directly via the action on the page. This begins the pageflow. Before I was trying to call a transition of the pageflow before it had ever been started.
