[jboss-user] [JBoss Seam] - Re: jBPM can't evaluate method

[smithbstl]

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

  |     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  |     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>

Here is the link I am using to call the Transition.  It is in the context of an h:dataTable column.

        <h:column>
  |             <f:facet name="header">
  |                 <h:outputText value="#{msgs['ServiceRequestList.action']}"/>
  |             </f:facet>
  |             <h:commandLink id="viewRequestsLink" 
  |                     action="viewRequests" 
  |                     rendered="#{not empty addressRow.requestCollection}" 
  |                     value="#{msgs['AddressList.viewRequest']}">
  |            </h:commandLink>
  |         </h:column> 

When I click the link, the page just reloads, the transition is never activated.  Its driving me nuts.

Thanks for any help
