Summary:
   Fix NullPointerException in SimpleActionIdHandler.generateActionID()
 
Problem Description:
   The NullpointerException mentioned above can occur when during the request flow a session is created for the anonymous user, while it wasn't there initially(Init Phase). This problem could be circumvented, by either setting public.session=true in NavigatorService, which causes some memory overhead, or by preventing that a session gets created at all. So please check custom code on whether session creation may be circumvented. Given that suggestions above can not be enforced, this APAR makes product code more robust on scenario mentioned above
 
Problem Solution:
   Call init() on SimpleActionIdHandler to make sure action counter is always initialized.
 
Failing Module(s):
   Engine: State handling
