Why would you only want to process the first item in the list?<br><br>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:<br><br>rule 1<br>
when<br> $p : Parent( $mess : message );<br> $s : List<String>() from $p.segments;<br>then<br> if($s.size() > 0) {<br> String segment = $s.get(0);<br> insertLogical(new ParentSegment($p, $mess, segment) );<br>
end<br><br>rule 2<br>when<br> ParentSegment( $p : parent, $mess : message, $segment : segment )<br>then<br> ....<br>end<br><br><div class="gmail_quote">2011/3/18 Sébastien Raickman <span dir="ltr"><<a href="mailto:sebastien.raickman@gmail.com" target="_blank">sebastien.raickman@gmail.com</a>></span><br>

<br>Or the way to cast segments in (String []) in the following rule:<br>
<br>dialect "mvel"<br><br>when<br> $m : Parent();<br>
$mess : Message() from $m.message;<br> $seg : String[]() from $m.<b>segments</b>;<br><br>my error at deployment of drools-server is :<br><br><i><b>unqualified type in strict mode for: segments]</b></i><br><br>Thanks in advance<br>
