Re: [rules-users] How to use not operator in drool.

Hi ALL, I am using drool4.0.1 in my application i am able to use IN,OR,AND operator but i am facing problem in using not operator. my requirement of not operator is just like a not gate. the way i am using it is : eval(not((Map( this["city"] !="mumbai"))||(Map( this["city"] =="delhi")))) so can you please help me out to solve this problem: should i use not operator or some thing else in drool.
