Creating parent->child using CML: Not Possible?

Dear Alfrescians

I've posted here http://forums.alfresco.com/en/viewtopic.php?f=27&t=35369 about an issue regarding the use of CML to create a folder structure ie
parentFolder->
childFolder1 childFolder2 .. childFoldern.
Typically this scenario would be provoked by a "student registration" event; The parentFolder being their name+identifier with childFolders such as Assessment, Finance, Admissions etc. I've been able to create the parentFolder using CML:

public class CreateContentServlet extends HttpServlet{
   private String folder = "";   
   private static Log log = LogFactory.getLog(CreateContentServlet.class);
   
   @Override
   protected void doGet(HttpServletRequest request, HttpServletResponse response)
         throws ServletException, IOException {
      System.out.println("doGet called");
      folder = request.getParameter("folder");   
      System.out.println("doGet: Calling createContent with " + Attributes.PARENT_FOLDER + " as parent");
      createContent(request, response,  Attributes.PARENT_FOLDER, folder);                  
   }
   

   @Override
   protected void service(HttpServletRequest req, HttpServletResponse resp)
         throws ServletException, IOException {
      System.out.println("service called");
      super.service(req, resp);
   }
   
   private void createContent(HttpServletRequest request, HttpServletResponse response, String parent, String folder) throws IOException
   {
      
      // Start the session
      AuthenticationUtils.startSession(Attributes.USERNAME, Attributes.PASSWORD);         
      try {
         // Make your web service call in here
         createFolder(parent, folder, request, response);
      }
      catch (Throwable e) {
         log.error("createContent erorr: " + e.toString());
         e.printStackTrace();
      }
      finally {
         // End the session
         AuthenticationUtils.endSession();
      }    
    }
   
   protected static void createFolder(String parent, String folder, HttpServletRequest request, HttpServletResponse response) throws Exception
    {
      final Store STORE = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
      // The default workspace store is SpacesStore
       //Store storeReference = new Store(Constants.WORKSPACE_STORE, "SpacesStore");

       // We want to create a new folder or workspace called child in the parent folder under company home
       // Create parent reference to the parent space in company home
       //ParentReference parentReference = new ParentReference(STORE, null, "/app:company_home/cm:parent",
      ParentReference parentReference = new ParentReference(
                    STORE,
                    null,
                    "/app:company_home/cm:" + parent,
                    Constants.ASSOC_CONTAINS,
                    Constants.createQNameString(Constants.NAMESPACE_CONTENT_MODEL, "sample_folder"));
                            
       NamedValue[] properties = new NamedValue[] { Utils.createNamedValue(Constants.PROP_NAME, folder) };
       CMLCreate create = new CMLCreate(
             "1",
             parentReference,
             null,
             null,
             null,
             Constants.TYPE_FOLDER, properties);      
       CML cml = new CML();
       cml.setCreate(new CMLCreate[] { create });
       UpdateResult[] results = WebServiceFactory.getRepositoryService().update(cml);
             
      
       }                                    
   
}

but if I attempt to create a simple parent->child structure using another instance of CMLCreate for the child folder:

public class CreateContentServlet extends HttpServlet{
   private String folder = "";   
   private static Log log = LogFactory.getLog(CreateContentServlet.class);
   
   @Override
   protected void doGet(HttpServletRequest request, HttpServletResponse response)
         throws ServletException, IOException {
      System.out.println("doGet called");
      folder = request.getParameter("folder");   
      System.out.println("doGet: Calling createContent with " + Attributes.PARENT_FOLDER + " as parent");
      createContent(request, response,  Attributes.PARENT_FOLDER, folder);                  
   }
   

   @Override
   protected void service(HttpServletRequest req, HttpServletResponse resp)
         throws ServletException, IOException {
      System.out.println("service called");
      super.service(req, resp);
   }
   
   private void createContent(HttpServletRequest request, HttpServletResponse response, String parent, String folder) throws IOException
   {
      
      // Start the session
      AuthenticationUtils.startSession(Attributes.USERNAME, Attributes.PASSWORD);         
      try {
         // Make your web service call in here
         createFolder(parent, folder, request, response);
      }
      catch (Throwable e) {
         log.error("createContent erorr: " + e.toString());
         e.printStackTrace();
      }
      finally {
         // End the session
         AuthenticationUtils.endSession();
      }    
    }
   
   protected static void createFolder(String parent, String folder, HttpServletRequest request, HttpServletResponse response) throws Exception
    {
      final Store STORE = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
      // The default workspace store is SpacesStore
       //Store storeReference = new Store(Constants.WORKSPACE_STORE, "SpacesStore");

       // We want to create a new folder or workspace called child in the parent folder under company home
       // Create parent reference to the parent space in company home
       //ParentReference parentReference = new ParentReference(STORE, null, "/app:company_home/cm:parent",
      ParentReference parentReference = new ParentReference(
                    STORE,
                    null,
                    "/app:company_home/cm:" + parent,
                    Constants.ASSOC_CONTAINS,
                    Constants.createQNameString(Constants.NAMESPACE_CONTENT_MODEL, "sample_folder"));
                            
       NamedValue[] properties = new NamedValue[] { Utils.createNamedValue(Constants.PROP_NAME, folder) };
       CMLCreate create = new CMLCreate(
             "1",
             parentReference,
             null,
             null,
             null,
             Constants.TYPE_FOLDER, properties);      
       CML cml = new CML();
       cml.setCreate(new CMLCreate[] { create });
       UpdateResult[] results = WebServiceFactory.getRepositoryService().update(cml);
      
       //add child
       CMLCreate createChild = new CMLCreate(
             "2",
             parentReference,
             "1",
             Constants.ASSOC_CONTAINS,
             Attributes.EMAIL_FOLDER,
             Constants.TYPE_FOLDER, properties);      
             
       cml.setCreate(new CMLCreate[] { createChild });
       UpdateResult[] result = WebServiceFactory.getRepositoryService().update(cml);
      
       }                                    
   
}
I get an error:

The problem appears to be around creating a sub-folder beneath a folder that was originally created using CML. I tested this by creating a folder using CML called testParent, then attempted to create a sub-folder using my class. It's not happy with this scenario.

Can someone confirm for me whether it's possible to create a folder structure using CML such as this:
parentFolder->
childFolder1 childFolder2 .. childFoldern. A worked example would be an enormous help.

Thanks you.

Andrew
