Re: [rules-users] Using java.util.List in rules

Yes I'm Brazilian.... I need to improve my english I now hehehe About the problem... I solved it. But now I'm getting this error when I use a static property in the rules: Exception in thread "AWT-EventQueue-0" org.drools.RuntimeDroolsException: Exception executing predicate org.drools.base.mvel.MVELPredicateExpression@916f80 at org.drools.rule.PredicateConstraint.isAllowed( PredicateConstraint.java:197) at org.drools.reteoo.FromNode.assertTuple(FromNode.java:70) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple( SingleTupleSinkAdapter.java:29) at org.drools.reteoo.EvalConditionNode.assertTuple( EvalConditionNode.java:150) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple ( SingleTupleSinkAdapter.java:20) at org.drools.reteoo.FromNode.assertTuple(FromNode.java:87) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple( SingleTupleSinkAdapter.java:20) at org.drools.reteoo.FromNode.assertTuple (FromNode.java:87) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple( SingleTupleSinkAdapter.java:20) at org.drools.reteoo.FromNode.assertTuple(FromNode.java:87) . . .

Did you know why? If I use de value like this " valor.codValor == 154", I have no problem. 2007/10/29, Edson Tirelli <tirelli(a)post.com&gt;: > > > Anderson, > > What is the error?
