I'm not sure what I did earlier, but when executing the below rules, I get
the desired results. I insert 20 Alert objects and the rule collects alerts
according to a specific case number, rules and output below
Rules
rule 'Group alerts for a specific case'
dialect 'java'
when
Alert( $caseNumber : caseNumber, $alertNo: alertNo )
$list : List( ) from collect($alert : Alert( caseNumber == $caseNumber))
then
insertLogical($list);
end
rule 'Print inserted lists'
salience -10
dialect 'java'
when
$list : List( )
then
System.out.println("******Printing list******: ");
System.out.println("******List hashCode: " + $list.hashCode());
for(Object o : $list){
System.out.println(o);
}
end
Output
******Printing list******:
******List hashCode: -1902211073
Alert [caseNumber=1021567, alertNo=1]
