[rules-users] verifying 'is not null' in decision table?

How can I verify if my condition attribute is not null in decision table? I have a class - Public Class Person { String firstName = null; String lastName = null ; } In my decision table I have to check if firstName and lastName are not null and then fire actions. How I can do this? I know I can get that through drl. Thanks -- View this message in context: http://n3.nabble.com/verifying-is-not-null-in-decision-table-tp96386p9638...
