Re: [rules-users] Change Notification doesn't work with eval(true) in one of the rules

All the rules defined in a single DRL were running fine until one day we added eval(manager.isEnabledSomeSettings()) into one of the rule in drl, which causing an issue for change update on the fly (see below error stacks). When we changed that eval to Boolean(this == Boolean.TRUE) from manager.isEnabledSomeSettings() then the change notification getting back to work properly. Any ideas?
