Re: [rules-users] Some Questions related to execution
"or" causes two rules to be generated internally hence the double activation
you report.
i.e. the following are generated internally:-
rule "internal 1"
when
Person ( gender == "Female" )
then
resultIds.add("id_1000")
end
rule "internal 2"
when
Procedure( needToDone == "ABC" )
then
resultIds.add("id_1000")
end
There are different ways to tackle the duplicate; (1) prevent it from
occurring in the first instance, (2) remove duplicates afterwards, both of
which are simplified if "resultIds" becomes a Fact rather than presumably a
global (although still possible).
(1)
rule "rule"
when
(
Person ( gender == "Female" )
or
Procedure( needToDone == "ABC" )
)
not ResultId( value == "id_1000" )
then
insert(new ResultId("id_1000"));
end
(2)
rule "rule"
salience 0
when
Person ( gender == "Female" )
or
Procedure( needToDone == "ABC" )
then
insert(new ResultId("id_1000"));
end
rule "remove duplicates"
salience 1000
when
$orig : ResultId( $v : value)
$dup : ResultId( this != $orig, value == $v )
then
remove( $dup )
end

1) If I have a Rule definition
when
#conditions
Person( gender == "Female")

then
resultIds.add("id_1000");
Is it not short circuit If first condiiton matches?
I get twice time "id_1000" in resultIds.
2) How can I chekc the multiple existence
For Example:
How can I chekc that multiple instances of Procddure have alredayDone= "ABC
"
Rule Definition only chekc once:
Procedure (alredayDone == "ABC")
