[jboss-user] [JBoss Seam] - Form not submitting using PageFlows

[smithbstl]

I have a weird problem using pageflows.  I have a h:commandLink in a datatable that has an action pointing to a transition in a pageflow.  When just the action of the commandLink is set, the form never gets submitted and hence my DataModelSelection component is not set.  When I throw in an arbitrary actionListener on the commandLink, the form is submitted and all is well.  I think I am missing something surely fundamental but can't see it.

When I take out the actionListener, selectedRequest is null, when I put it back in, selectedRequest returns the selected row of the DataModel

Here is the commandLink

<h:commandLink action="viewRequest"     actionListener="#{requestEntry.printSelectedRequest}"
  | value="#{msgs['ServiceRequestList.viewRequest']}"/>

The pageFlow

<pageflow-definition 
  |     xmlns="http://jboss.com/products/seam/pageflow"
  |     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  |     xsi:schemaLocation= "http://jboss.com/products/seam/pageflow http://jboss.com/products/seam/pageflow-1.2.xsd" 
  |     name="serviceRequestCreation">

  |     <start-page name="addressSearch" view-id="/AddressLookup.xhtml">
  |         <transition name="viewRequests" to="requestListing"/>
  |     </start-page>
  |     <page name="requestListing" view-id="/AddressRequestListing.xhtml">
  |         <redirect/>
  |         <transition name="viewRequest" to="serviceRequest"/>
  |     </page>
  |     <page name="serviceRequest" view-id="/ServiceRequest.xhtml">
  |         <redirect/>
  |     </page>
  | 
  | </pageflow-definition>
