Can anyone enlighten me why  the ManagedEntityIdentityInterceptor  is only 
added to a Seam component when the scope of the component is CONVERSATION?   
(-> org.jboss.seam.Component.initDefaultInterceptors() )


My understanding of the ManagedEntityIdentityInterceptor (which could be wrong) 
 is that it serves to ensure that Entities referenced by a stateful component 
such as a stateful session bean (SFSB) maintain their object identity within 
the JVM even across passivations and reactivations of this stateful component.  


Let's assume that we have a stateful session bean (SFSB) referencing an Entity 
instance, and the the scope of the SFSB is EVENT_Scope.   Since the scope is 
EVENT Scope and not CONVERSATION scope, no  ManagedEntityIdentityInterceptor is 
added to this SFSB.

Let's imagine further a situation where this SFSB is called multiple times 
during the life time of the EVENT scope.  For example, the SFSB could serve as 
backing bean for multiple JSF view components and be called multiple times 
during the render response JSF phase.

This raises the question: Can it happen that the EJB container passivates and 
then reactivates this SFSB between the different calls to this SFSB?  (I'd 
assume yes, but could be wrong).

If I'm not wrong with my "yes"-assumption, don't we need the  
ManagedEntityIdentityInterceptor added to this event-scoped SFSB component to 
maintain the object identity of any Entity instances referenced by the SFSB?

Thanks in advance for any answers.
