The following rules does not work with specific facts.
rule "rule1_long"
when
accumulate( Fact( $longVal: longVal), $minVal : min($longVal))
accumulate( Fact( $longVal2: longVal, $longVal2 > $minVal), $minVal2 : min($longVal2))
$minFact: Fact( longVal == $minVal)
$minFact2: Fact( longVal == $minVal2)
then
System.out.println("Rule ["+kcontext.getRule().getName()+ "] fires!");
Long $diff = (Long)$minVal2 - (Long)$minVal;
$minFact2.setDiff($diff);
// update($minFact2);
String errmsg = $diff == 0? " !!!!! ERROR !!!!!" : "";
System.out.println( drools.getRule().getName() + " diff：" + $minFact2.getLongVal() + " - " + $minFact.getLongVal() + " = " + $diff + errmsg);
System.out.println("\tretract <= "+$minFact );
retract($minFact);
end
There seems to be 2 kind of issues (root cause might be same though).
- 2nd accumulate return same min value with 1st one.
- rule fire count is less than expected.
This does not work with specific set of facts, but works with another set of facts.
If update is called for the fact like above commented out line, this does not happen.
