[rules-users] Difference between constraint within a pattern and eval

Hi There, I am facing a weird issue, following rule doesn't run rule "test" dialect "mvel" when Experience( primary == "SY") ) then log.debug("SY"); end but following works. :confused: rule "test1" dialect "mvel" when exp : Experience( eval(exp.getPrimary() == "SY") ) then log.debug("SY"); end Whats the difference between the two,mean why second works but the first one doesnt? I have used former expression in many other rules but haven't encountered this problem. Advance thanks for your response. --MRaj -- View this message in context: http://www.nabble.com/Difference-between-constraint-within-a-pattern-and-...
