Re: [rules-users] [drools 5.3.0.Final] Predicate ... must be a Boolean expression

Why are you using mvel 2.1 beta 6 ? I enforced this check on the 5.3.0.Final but in order to work it needs a fix I did on mvel. This fix (together with many other) has been deployed in a proper mvel release (2.1.0.drools4) especially made for this purpose. This is also the mvel version referenced in the drools pom. Please, replace the mvel version and let me know if it works in this way. I hope this helps, Mario -- View this message in context: http://drools.46999.n3.nabble.com/drools-5-3-0-Final-Predicate-must-be-a-...
