5.4.2.1 Event handling: Is a note needed stating how the producershould interpret eventsParams.portletStateChange

[Nathan E Lipke <nlipke@bea.com>]

In the following use-case the interpretation of 
eventsParams.portletStateChange may need to be clarified.

   1. The consumer sends a handle events message, such that:
         1. eventsParams.portletStateChange is "cloneBeforeWrite"
         2. eventParams.events contains
               1. event1
               2. event2
   2. The producer receives the message and dispatches the events to the
      portlet (in the order of event1 then event2)
         1. During processing of event1 a state change is made such that
            an implicit  clone occurs
         2. During then processing of event2 another state change happens
          * At this point another clone should not happen, rather the
            portletStateChange field is effectively
            "readWrite")

The note could read something like:

During an invocation of HandleEvents where the portletStateChange field 
is "cloneBeforeWrite" the producer MUST NOT clone the portlet more than 
once. The portlet may change its state after the clone, as though the 
portletStateChange field was "readWrite".

Thanks,

Nate
