[jboss-user] [JBoss Seam] - Problem with DataModel and s:link

[vfaid]

Hello,

I'm using Seam 2.0GA.

I've a rich:dataTable that displays the values of a DataModel outjected from a "search" component. Each row defines a s:link with an action that triggers the call to a select method of an "info" component throuh a pageflow. The two components are in a the same conversation scope. 

It works fine if I use h:commandLink or h:commandButton but if i use s:link, it fails. The value passed to the select method is always the one that's attached to first row I've clicked.

Here are the code snippets.

SearchBookingAction:

  | @Stateful
  | @Scope(ScopeType.CONVERSATION)
  | @Name("search")
  | @Restrict("#{identity.loggedIn}")
  | public class SearchBookingAction implements SearchBooking {
  | 
  |     @In
  |     private EntityManager arsEntityManager;
  | 
  |     @DataModel
  |     private List<Booking> bookings;
  | 
  |     private String pnr;
  |     private String flightNumber;
  |     private Date flightDate;
  | 
  |     public void search()
  |     {
  |         Query query = arsEntityManager.createQuery(...);
  |         bookings = query.getResultList();
  |     }
  | 
  |     ....
  | }
  | 

BookingInfoAction:

  | @Stateful
  | @Scope(ScopeType.CONVERSATION)
  | @Name("info")
  | public class BookingInfoAction implements BookingInfo {
  | 
  |     @In
  |     private EntityManager arsEntityManager;
  |     
  |     private Booking booking;
  | 
  |     private List<Flight> departureFlights;
  |     private List<Flight> returnFlights;
  | 
  |     public void selectBooking(Booking booking) {
  |         this.booking = booking;
  |     }
  | 
  |     public boolean populate() {
  |         log.info("info.populate() called with: "+booking.getPnr());
  |         if (booking == null)
  |             return false;
  |         departureFlights = selectDepartureFlights();
  |         returnFlights = selectDepartureFlights();
  |         return true;
  |     }
  | 
  |     ...    
  | }
  | 

search.xhtml:

  | <rich:dataTable value="#{bookings}" var="currentBooking" >
  | 	<rich:column>
  | 	    <f:facet name="header">#{messages['asr.list.pnr']}</f:facet>
  | 	    #{currentBooking.pnr}
  | 	</rich:column>
  | 	<rich:column>
  | 	    <f:facet name="header">#{messages['asr.list.name']}</f:facet>
  | 	    #{currentBooking.masterName}
  | 	</rich:column>
  | 	<rich:column>
  | 	    <f:facet name="header">#{messages['asr.list.flightnum']}</f:facet>
  | 	    #{currentBooking.masterFlightNumber}
  | 	</rich:column>
  | 	...
  | 	<rich:column>
  | 	    <f:facet name="header">#{messages['asr.list.viewheader']} :</f:facet>
  | 	    <s:link value="#{messages['asr.list.view']}" action="view" />
  | 	</rich:column>
  | </rich:dataTable>
  | 

bo.jpdl.xml:

  | <start-page name="displaySearchBookingForm" view-id="/search.xhtml">
  | 	<redirect/>
  | 	...
  | 	<transition name="view" to="populateBookingInfo">
  | 	    <action expression="#{info.selectBooking(currentBooking)}" />
  | 	</transition>
  | </start-page>
  | 
  | <decision name="populateBookingInfo" expression="#{info.populate()}">
  | 	<transition name="true" to="displayBooking"/>
  | 	<transition name="false" to="displayFindBookingForm"/>
  | </decision>
  | 
  | <page name="displayBooking" view-id="/booking.xhtml" back="enabled">
  |         <redirect/>
  | 	...
  | </page>
  | 
  | ...
  | 


Any ideas why it works with a h:commandButton or h:commandLink and not a s:link?
