[rules-users] Drools mvel strict type

[Michael Anstis]

Why would you only want to process the first item in the list?

That aside, If you really only want to evaluate the first String in the list
you might be better off using two rules, something like this:

rule 1
when
    $p : Parent( $mess : message );
    $s : List<String>() from $p.segments;
then
    if($s.size() > 0) {
        String segment = $s.get(0);
        insertLogical(new ParentSegment($p, $mess, segment) );
end

rule 2
when
    ParentSegment( $p : parent, $mess : message, $segment : segment )
then
    ....
end
