                 Key: WFCORE-1440
                 URL: https://issues.jboss.org/browse/WFCORE-1440
             Project: WildFly Core
          Issue Type: Bug
          Components: Domain Management
    Affects Versions: 2.1.0.CR1
            Reporter: Tomaz Cerar
            Assignee: Tomaz Cerar


ExpressionResolverImpl#resolveExpressionsRecursively

does 
{code}
else if (type == ModelType.LIST) {
            resolved = node.clone();
            ModelNode list = new ModelNode();
            for (ModelNode current : resolved.asList()) {
                list.add(resolveExpressionsRecursively(current));
            }
            resolved = list;
        } 
{code}
for list attributes, but in case that resolved value is empty list it would return list that is undefined instead of empty list.
