[rules-users] [rule-users]runtime polymorphic support?

Edson, sorry for my confusing question. Yes am asked same question. Related to this i have one more. if my ClassA is as abstract will it work? is there any constraints? please clarify Thanks and Regs, basha //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Hi, Sorry, I did not understood your question, but I guess you are asking about facts matching ObjectTypeNodes of super classes. The answer is yes, it works: public class A {} public class B extends A {} public class C extends A {} If you have a rule saying rule XXX when A () then // do something end The rule will fire for all facts of class A, B and C, as B and C are subclasses of A. It is like if you did an "instanceof" to know what rules will fire and what will not. Hope that is what you were asking. []s Edson
