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?
