Hi! In a split constraint i've: $bool:Boolean(booleanValue==true) from hbnSession.createQuery("select active from Euristic where name=:name").setString("name","C").uniqueResult() eval($bool) but the result is: XOR split could not find at least one valid outgoing connection for split C_isActive? hbnSession is an active hibernateSession In a simple drl rule, this works fine. unfortunately, the previous post (slidingTime) is yet unresolved. :( Thanks in advance. *Francesco*
