Here is the sample rules:
rule "level_pressure_2"
when
exists Person();
$person : Person (dangerLevel <3, upBloodPressure >=180 ,
downBloodPressure >=90 )
then
#actions
$person.setDangerLevel($person.getDangerLevel() +1);
end
rule "level_pressure_3"
when
#> exists Person();
$person : Person (hisAge : age -> (safeAge(hisAge, 27,20)));
then
System.out.println("----------->"+hisAge);
end
---- end ---
Now when I commented out one "exists" line, it works fine. But when there
are more than one "exists" in one drl, it throws following exception:
java.lang.ClassCastException
