Hi, When I pointed the rules from Drools 4.0.7 to Drools 5.0.0M2, I'm getting the following errors at runtime. I also tried Drools 5.0.0M3 (same error). The error occurs while adding a package. Could someone help me? Do I've to do something differently for 5.0.0M2? java.lang.NullPointerException at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:420) at org.drools.reteoo.ReteooRuleBase.addPackage(ReteooRuleBase.java:381) Thanks, Jagathesh _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
