Hi,

While trying to add a cluster-ref element under lb-config, following error occurs:

What does "No corresponding property found for method" mean? Am I doing something wrong here?

        public void decorate(AdminCommandContext context, final LbConfig instance) throws TransactionFailure, PropertyVetoException {

                            instance.setName(clusterRef+"-http-lb-config");
                            ClusterRef newClusterRef = instance.createChild(ClusterRef.class);
                            newClusterRef.setRef(clusterRef);
                            instance.getClusterRefOrServerRef().add(newClusterRef);
        }

Thanks,
