I want to do binding of UIDatascroller with my UI. For this I have made two action classes of scope Event and Session. The Problem I am facing is that whenever I try to get value from Event Scope class in Session scope class I always get a null value although the variable in not null in Event scoped class.

Below is my Class with Event Scope

package com.pcounts.server.action.sp;

import java.util.List;
import java.util.Set;
import java.util.Vector;

import javax.faces.component.UIData;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Factory;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Out;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.datamodel.DataModel;
import org.richfaces.component.UIDataTable;
import org.richfaces.component.UIDatascroller;

import com.pcounts.server.action.auth.PCUserSession;
import com.pcounts.server.hibernate.pojo.Printerscans;
import com.pcounts.server.hibernate.service.GroupService;
import com.pcounts.server.hibernate.service.PrinterScansService;
import com.pcounts.server.hibernate.service.UserService;

@Name("factoryClass")
@Scope(ScopeType.EVENT)
public class FactoryClass {
     
     @In(create = true) PrinterScansService printerScansService;
     @In(create = true) GroupService groupService;
     @In(create = true) PCUserSession pcUserSession;
     @In(create = true) UserService userService;
     @In(create = true) SalesPersonDashboardBean SalesPersonDashboard; 
     
     @DataModel
     private List<Printerscans> lstPrinterscans;
     
     UIDataTable dashboardDataTable;
     UIDatascroller dashboardDataScroller;
     
     @Factory("lstPrinterscans")
     public void listPrinterscans() {
          System.out.println("----- OrderField ----- "+ SalesPersonDashboard.orderField);
          List listSubSetRecords;
          List lstGroups;
          Set setSPsOfGroups;
          int pageFirstIndex;
          Long count;

          lstGroups = groupService.getGroupsForSP(pcUserSession.getUserNumber());

          setSPsOfGroups = userService.getSPsFromSalesGroups(lstGroups);

          count = printerScansService.getPrinterscanRowCount(userService
                    .getCSVUserNumber(setSPsOfGroups));

          Vector vector = new Vector();

          vector.setSize(count.intValue());

          pageFirstIndex = (this.getDashboardDataScroller().getPage() * getDashboardDataScroller()
                    .getDataTable().getRows())
                    - this.getDashboardDataScroller().getDataTable().getRows();

          listSubSetRecords = printerScansService.getPrinterscansOfSPs(
                    userService.getCSVUserNumber(setSPsOfGroups), SalesPersonDashboard.orderField,
                    SalesPersonDashboard.ascendingOrder, pageFirstIndex);

          
          
          for (int index = 0; index < listSubSetRecords.size(); index++) {
               vector.set(pageFirstIndex + index, listSubSetRecords.get(index));
          }

          lstPrinterscans = vector;
     }
     
     public void nullList(){
          this.lstPrinterscans = null;
     }

     public UIDatascroller getDashboardDataScroller() {
          return dashboardDataScroller;
     }

     public void setDashboardDataScroller(UIDatascroller dashboardDataScroller) {
          this.dashboardDataScroller = dashboardDataScroller;
     }

}

And this is the class with Session Scope.

@Scope(ScopeType.SESSION)
@Name("SalesPersonDashboard")

public class SalesPersonDashboardBean {
     
     @In(required = false)
     FactoryClass factoryClass;
     public boolean ascendingOrder;
     public String orderField;
     
     public void sortAction(String field) {
          System.out.println("-----Field----- " + field);
//          System.out.println("-----Ascending Order----- " + ascendingOrder);
          this.ascendingOrder = !this.ascendingOrder;
          this.orderField = field;
//          System.out.println("-----order Field----- " + orderField);
//          factoryClass.dashboardDataScroller.setPage(1);
//          System.out.println("DataScroller Page: " + factoryClass.dashboardDataScroller.getPage());
          factoryClass.listPrinterscans();
     }

And the output which I get in Console is

13:10:42,015 INFO  [STDOUT] ----- OrderField ----- null
13:11:02,796 INFO  [STDOUT] -----Field----- locations.locationName
13:11:02,812 INFO  [STDOUT] ----- OrderField ----- null

I want to get non-null value of the SalesPersonDashboard.orderField and SalesPersonDashboard.ascendingOrder in pcFactory class

Please sort out this problem as soon as possible.
I'll be thankful to you.
Bye
