[rules-users] Is it here or not?
Consider these rules:
rule "no Ax Or Ax 1"
when
EventA(id == "1") and Boolean( $v: booleanValue == true )
or
(not EventA(id == "1")) and Boolean( $v: booleanValue == false )
then
System.out.println( "#1: A(1) is " + $v );
end
rule "no Ax Or Ax 2"
when
(EventA(id == "1") or not( EventA(id == "1") ))
List( $size: size ) from collect( EventA(id == "1") )
then
boolean v = $size > 0;
System.out.println( "#2: A(1) is " + v );
end
Rules #1 and #2 fire as expected while inserting lots of
EventA(id=="1"), once for each new one.
Rule #1 fires as expected after retracting the last inserted fact.
Rule #2 does not, BUT if I split the rule manually in two, they both fire:
...when
EventA(id == "1")
List(...
and
...when
not( EventA(id == "1") )
List(...
Using 5.1.1.
