Problem with conversation!! HELP

[manuel.gentile]

I have this Session Bean Stateful

@Local
public interface Report {
public String cercaComune();
public void destroy();
}

@Stateful
@Name("report")
@Interceptor(SeamInterceptor.class)
public class ReportImpl implements Report, Serializable {
protected static final Logger log = Logger.getLogger(ReportImpl.class);
@PersistenceContext
protected EntityManager em;

public String cercaComune() {
log.info("Query comune:" + "");//queryComune.getNome());
List comuni = em.createQuery("from Comune c where c.nome like :search")
.setParameter("search", "%")//queryComune.getNome() + "%")
.setMaxResults(10)
.getResultList();
return "redisplay";
}

@Destroy
@Remove
public void destroy() {
log.info("destroyed");
}
}

immediately after i call report.cercaComune
i obtain
18:21:26,863 INFO [ReportImpl] Query comune:
18:21:26,972 INFO [ReportImpl] destroyed

WHY The conversation are removed from the context??????

[gavin.king]

What are your conversation and session timeouts?

[manuel.gentile]

This is conversation timeout

<context-param>
<param-name>org.jboss.seam.core.manager.conversationTimeout</param-name>
<param-value>120000</param-value>
</context-param>

for the Session i did not set any value!

I turn back to a precedent version of Seam (not the last CVS) and after few second of inactivity i have

javax.servlet.ServletException: Could not start transaction
javax.faces.webapp.FacesServlet.service(FacesServlet.java:109)
org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:122)
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)

root cause

java.lang.IllegalStateException: Could not start transaction
org.jboss.seam.jsf.SeamExtendedManagedPersistencePhaseListener.beforePhase(SeamExtendedManagedPersistencePhaseListener.java:30)
org.apache.myfaces.lifecycle.LifecycleImpl.informPhaseListenersBefore(LifecycleImpl.java:520)

org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:122)
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)


I think i have problem with the configuration.

Can you help me?
