Re: [rules-users] Rule problem

Thanks for the answer! But I sometimes get 2 rules that are correct, and that is impossible. I embedded Greg's DroolsTest class in my class (I am doing some test on performance and studying the difference between performance with a plain java class), and it still doesn't work, and I really don't see why. Anyone any suggestions, in attachement, my class.
