> Also this configuration is OK:
> <drools:ksession id="statefulSession" type="stateful" kbase="kbase1">        
>            <drools:workingMemoryEventListener>
>                <bean class="org.drools.event.DebugWorkingMemoryEventListener"/>
>            </drools:workingMemoryEventListener>       
> </drools:ksession>
> Exception occurs only when both listeners are configured.
> probably because of bad position of elements; when listeners configured inside
> <drools:ksession> as shown above, current order required:
> agendaEventListener
> processEventListener
> workingMemoryEventListener
> but when configured through <drools:eventListeners> element and listeners
> attribute in <drools:ksession> element, order of event listeners does not
> matter. I think this is because of <xsd:all> resp. <xsd:sequence> inside
> drools-spring.xsd.
> It would by nice to unite both styles of configuration.
