how set vertion_label of a component in virtual document with DFS

Hi all.

I'm trying to create virtual document with DFS and I need to explicitly set the version of a component.

How can i do this with DFS?

I'm trying to do it like this


public void createVD(){

        ObjectIdentity identity = new ObjectIdentity();
        identity.setRepositoryName("repo");
        DataObject packO = new DataObject();
        packO.setIdentity(identity);
        packO.setType("my_type");
        PropertySet properties =  new PropertySet();
        properties.getProperties().add(new StringProperty("object_name", false, "vd_object_name"));
        properties.getProperties().add(new NumberProperty("r_is_virtual_doc", false, null, 1, null, null));
        packO.setProperties(properties);

        ObjectIdentity oi = new ObjectIdentity();
        ...
        ObjectIdentitySet ois = new ObjectIdentitySet();
        ois.getIdentities().add(oi);
        
        List<DataObject> docOL = getObjectService().get(ois, options).getDataObjects(); 
        DataObject docO = docOL.get(0);
        
        ObjectRelationship relation = new ObjectRelationship();
        relation.setTarget(docO);
        relation.setName("virtual_document");
        relation.setTargetRole("child");
        PropertySet ps = new PropertySet();
        ps.getProperties().add(new StringProperty("version_label", false, "1.1"));
        ps.getProperties().add(new NumberProperty("use_node_ver_label", false, null, 1, null, null));
        relation.setRelationshipProperties(ps);
            
        packO.getRelationships().add(relation);
        docO = client.update(docO, null);
        
        DataPackage dataPackage = new DataPackage(packO);
        getObjectService().create(dataPackage, operationOptions );

}
