ok, thank you so much for your help. It works. Thanks. But one tough question for you.
How can I know what was the reason a rule condition failed. Lets say rule when test( a == "b" ) then //consequence end I want to know what caused the condition a=="b" to fail was the value of a is "b" or anything else. and I need to log this to a log file. Somebody told me that Verifier does the trick, but we need to add some custom rules to get to the values. I tried to google lot on this. But I never got anything which do what I want to do. Please help me on this.
