cause if i would know that there hasnt been a change in the count of, for<br>
example, A.A, it shouldnt fire,<br>
<br>
that leads me to the next question: is an accumulate function excuted by<br>
more than one thread ?<br>

it rises if you think of storing such information in the context of the<br>
accumulate function directly. like a semaphore, which signals that this<br>
entry has already caused something fired<br>
<br>
in the example:<br>
the rule 1 accumulates over attributes of incoming objects (A.A) and also<br>
sets a flag if an entry has been changed (count ++)<br>
