Problem with passivation/activation

[mbolcina]

I have SFSB on SESSION scope. SFSB looks like this:

@Stateful
@Scope(ScopeType.SESSION)
@Name("dnListBean")
public class DnListBean extends ListManagerSimple<Dn> implements DnListLocal
{
 private Long resultCount;
 private List<Dn> resoultList;

 @PrePassivate
 public void prePasivate()
 {
 System.out.println("DnListBean.prePasivate()");
 System.out.println("resultCount="+resultCount);
 }

 @PostActivate
 public void postActive()
 {
 System.out.println("DnListBean.postActive()");
 System.out.println("resultCount="+resultCount);
 }

 ...
}

Problem is that when SFSB gets passivate (after some time if user does nothing on page) and then back activate (after user for eg. refresh page which uses this sesssion bean) all data is lost.

Here is log from console:

09:14:02,021 INFO [STDOUT] DnListBean.prePasivate()
09:14:02,022 INFO [STDOUT] resultCount=64
09:14:33,674 INFO [STDOUT] DnListBean.postActive()
09:14:33,674 INFO [STDOUT] resultCount=null

Am I missing something?
