RequestParameter is null in Stateful SB

[hsiung]

The RequestParameter in my EntityHome (WebServiceHome) is working correctly.

But when I transform this EntityHome in a Stateful SessionBean (adding @Stateful an implements the @Local interface)
the same RequestParameter is always null!

What am I doing wrong?

The WebServiceHome Stateful SB:

package com.csg.cs.wsrepository.session;

import javax.ejb.Remove;
import javax.ejb.Stateful;

import com.csg.cs.wsrepository.entity.WebService;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Begin;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.web.RequestParameter;
import org.jboss.seam.faces.Redirect;
import org.jboss.seam.framework.EntityHome;




@SuppressWarnings("serial")
@Stateful
@Name("webServiceHome")
public class WebServiceHome extends EntityHome<WebService> implements WebServiceInterface
{
   @RequestParameter String webServiceId;
   
    @Override
    public Object getId() {
         System.out.println("@RequestParameter webServiceId " + webServiceId);
         String webServiceId = (String) Redirect.instance().getParameters().get("webServiceId");
         System.out.println("@RequestParameter webServiceId " + webServiceId);
         if (webServiceId == null) {
               return super.getId();
          } else {
               return webServiceId;
          }
     }
        
    @Override
    public Class<WebService> getEntityClass() {
         setEntityClass(WebService.class);
         return WebService.class;
    }
    
    @Override @Begin
    public void create() {
         System.out.println("create webServiceId " + webServiceId);
         super.create();
         System.out.println("create webServiceId " + webServiceId);
     }
    
    public String persist()
    {
         String result = super.persist();
         System.out.println("**************** persist WebService");
         return result;
    }

    public String update()
    {
         String result = super.update();
         System.out.println("**************** update WebService");
         return result;
    }
    
    @Remove
    public String remove() {
         return "removed";
    }

}

I have a problem just like this.

Actually, as soon as I enter the page, the @RequestParameter variable is set correctly (as seen on debug mode), but when I press a button to call another method that reads the same variable, it is always null !

The SessionBean is also @Stateful.

Anyone knows how to fix it ??

Just to let you know, I was able to keep the variable value by adding
@Scope(ScopeType.SESSION)
in the class.
