To: rules-users(a)lists.jboss.org Date: Friday, February 19, 2010, 10:31 AM I have considered doing a custom operator contains all too. Can't I use the eval for this though like the example below? I haven't tried it yet.  class SampleObject{    List IDs; } rule "test" no loop   when         $h3: Set() from RefData.getIDs()         r1: SampleObject()         eval ( $h3.containsAll( r1.IDs) )    then         error() end -- View this message in context: http://n3.nabble.com/Can-I-do-a-Collection-contains-Collection-tp217546p2...

when I replace Zipcode with type "int" as that is my type drools throws me an error saying it doesn't recognize the class. Is there some special way to declare primitive types?
