Re: [rules-users] How to write Drools rule basing on a changed property?

Requirement: 1) Rule When Person.address.address1 is changed THEN 2) Ideally we should have 2 objects, 1 for the old person instance, the other for the new person instance so contextually the LHS equals to oldPerson.address.address1 != newPerson.address.address1. A properties change listener might not be the best solution as it might span multiple calls and the property change could be done on the web layer which is out of the JBoss Drools knowledge session.
