[rules-users] how to use only updated value in drools
I am having a drl file with 2 rules The 1st rule updates a attribute, say updates attribute b to 10 based on some condition. The 2nd rule has a check for values with b not equal to 10. It logs error for those values not equals to 10. The b value gets updated to 10 in rule 1. However in the second rule it does not use updated value and logs error. Is there a way to use the updated b value in the 2nd rule. I tried using modify but still the error gets logged. -- View this message in context: http://drools.46999.n3.nabble.com/how-to-use-only-updated-value-in-drools-tp4017626.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Modifying the condition does not fix the issue It seems even though the value of b was modified to 10 in the first rule. It considers b as only blank (initial value) in the When clause of second rule.However in sysout the value of b appears properly as 10 -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-how-to-use-only-updated-value-in-drools-tp4017628p4017641.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] how to use only updated value in drools
Are you sure the first rule is fired? I tried out a similar program locally and it works fine. If the first rule is fired and you are updating the fact in the consequence of first rule, then certainly the second rule wont be fired.
