yang model:

augment "<path>tables/routes" {
case linkstate-routes-case {
container linkstate-routes {
list linkstate-route {
...
}

Works fine with InstanceIdentifier constructed like this:

iid = InstanceIdentifier.create(..).child(Tables.class, new TablesKey(..))
.child(LinkstateRoutes.class).child(LinkstateRoute.class, new LinkstateRouteKey(this.linkNlri));

But when the container is moved to grouping:

grouping linkstate-routes {
container linkstate-routes {
list linkstate-route

}

augment "<path>tables/routes" {
case linkstate-routes-case {
uses linkstate-routes;
}

The instance identifier gives following compilation error:

Bound mismatch: The generic method child(Class<N>) of type InstanceIdentifier<T> is not applicable for the arguments (Class<LinkstateRoutes>). The inferred type LinkstateRoutes is not a valid substitute for the bounded parameter <N extends ChildOf<? super Tables>>
