Re: [rules-users] null checking

How do I evaluate null conditions in the following case for example? seller: ( seller.cheese != null && seller.active == true ) cheese: ( cheese.type == "chedder" ) from seller.cheese In the above example seller.cheese is null but seller is used in the second part of the rule since we can't evaluate facts for null for some reason how do you check for a null condition. -- View this message in context: http://www.nabble.com/null-checking-tp20015953p20015953.html Sent from the drools - user mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
