<br>
nothing on the LHS (between when and then) matters when a rule fires; so eval()
and all other CEs are evaluated when facts are inserted.<br>
<br>
So, trying to get rid of the eval's would be worthwhile.<br>
<br>
The second thing (and I agree with Michael) is that you shoudl get rid of
collect, which causes the delay during insertion. I'd also use a Collector fact
with attributes for deal, a booking rule and a count.<br>
<br>
rule addCollector<br>
when<br>
$deal: </span></font><font size=2 color=black
face="Courier New"><span lang=EN-GB style='font-size:10.0pt;font-family:"Courier New";
color:black'>MarketDealModel()<br>
not (Collector( deal == $deal )<br>
then<br>
insert( new Collector( §deal ) );<br>
end<br>
<br>
When there is a matching Collector and a BTExecutionBookingRuleModel matches </span></font>the
deal:<br>
then<br>
modify the collector by incrementing the count and storing the matched
booking rule<br>
<br>
At a lower salience, add 2 rules matching a collector with count == 1 and count
!= 1 with obvious consequences. (The second one could switch to the next level
activation group.)<br>
