Hi im using datatable to display the values dynamically..
when the users fill the rows of data and insert immedietly the values are inserting , but when the keep page ideal for some time and insert the values are returning as null.
I have a pasted sample of my JSF and Bean class.

JSF page

<rich:dataTable  value="#{states}"  id="dt" var="f1" style=" width : 100%">


<rich:column style=" width : 10%;">

<h:inputText   value="#{f1.region}" />

</rich:column>

<rich:column style=" width : 10%;">

<h:inputText   value="#{f1.stateName}" />

</rich:column>

<rich:column style=" width : 13%;">

<h:selectOneMenu value="#{addCity[f1]}">


<f:selectItems value="#{stateItem}" />

</h:selectOneMenu>

</rich:column>


</rich:dataTable>

Bean Class

@Name("test")

@Stateful

@Scope(SESSION)

@Synchronized(timeout=1000000)

public class TestAction implements Test,Serializable

{


@PersistenceContext(type=PersistenceContextType.EXTENDED)

     private EntityManager em;


@Out(required=false)

     List <TblStatesCapital> states;


@Out(required=false,scope = SESSION)

     Map<TblStatesCapital, String> addCity;

}

After i submit immedietly the values are hitting my bean but after some times the values are coming null


Thanks and regards
