[rules-users] Accessing List<String> with mvel in condition

Hi, I've tried several options but none working so I welcome any help. * I'm using Drools 5.1.1. * I succesfully insert several List<String> into Working Memory and I'm able to printout them with a debug rule. * The problem is, when I try to access a position in a list I get no match even though I have values that should match. Here is the relevant code: rule "B Number has characters other than numbers" dialect "mvel" when $traffic_row : List(this[5] matches "[^0-9]") then System.out.println("row found" + $traffic_row) end Thank you in advance -- View this message in context: http://drools.46999.n3.nabble.com/Accessing-List-String-with-mvel-in-cond...
