[rules-users] evaluating different aspects of the same event

[Andre]

cause if i would know that there hasnt been a change in the count of, for
example, A.A,  it shouldnt fire, 

that leads me to the next question: is an accumulate function excuted by
more than one thread ? 

it rises if you think of storing such information in the context of the
accumulate function directly.  like a semaphore, which  signals that this
entry has already caused something fired

in the example:
 the rule 1 accumulates over attributes of incoming objects  (A.A) and also
sets a flag if an entry has been changed (count ++)
