CMIS: populating properties (type and aspect)

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I was helped out a while back in this community in this thread, and I was able to get things working well enough in my local test environment (4.1.7.3 Enterprise).  Now it's time to get it to work on what will become the production environment (4.2.f for now) and it's failing to populate a property.  Here's the code I'm using, with the following provisos:

- the session is established and is working
- the document specified by "id" is there, and is being accessed
- the propertyName parameter is valid
- the propertyValue parameter is valid

All that it's not doing is setting a property, and if I set a property manually the log.debug instruction at the bottom returns null (even in the working environment).

Any thoughts?

private static void changeProperties(String id, String propertyName, String propertyValue)
   {
      AlfrescoDocument alfDoc = (AlfrescoDocument) session.getObject(id);
   
      PropertiesImpl properties = new PropertiesImpl();
      List<CmisExtensionElement> extensions = new ArrayList<CmisExtensionElement>();
   
      CmisExtensionElement valueElem = new CmisExtensionElementImpl(
            ALFRESCO_EXTENSION_NAMESPACE, VALUE, null, propertyValue); 
      
      List<CmisExtensionElement> valueElems = new ArrayList<CmisExtensionElement>();
      valueElems.add(valueElem);
   
      List<CmisExtensionElement> children = new ArrayList<CmisExtensionElement>();
      Map<String, String> attributes = new HashMap<String, String>();
      attributes.put(PROPERTY_DEFINITION_ID, propertyName);
      children.add(new CmisExtensionElementImpl(ALFRESCO_EXTENSION_NAMESPACE,
            PROPERTY_STRING, attributes, valueElems));
   
      List<CmisExtensionElement> propertyValuesExtension = new ArrayList<CmisExtensionElement>();
      propertyValuesExtension.add(new CmisExtensionElementImpl(
            ALFRESCO_EXTENSION_NAMESPACE, PROPERTIES, null, children));
   
      CmisExtensionElement setAspectsExtension = new CmisExtensionElementImpl(
            ALFRESCO_EXTENSION_NAMESPACE, SET_ASPECTS, null,
            propertyValuesExtension);
      extensions.add(setAspectsExtension);
      properties.setExtensions(extensions);
      String repId = session.getRepositoryInfo().getId();
      Holder<String> objectIdHolder = new Holder<String>(alfDoc.getId());
      session.getBinding().getObjectService().updateProperties(repId, objectIdHolder, null, properties, null);
      
      log.debug((alfDoc.getPropertyValue(propertyName)).toString());
   }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I can't figure out why you are using CmisExtensionElement for your properties and aspect? If you are using the Alfresco OpenCMIS Extension you can simply set the properties and add the aspects per the examples on <a href="https://code.google.com/a/apache-extras.org/p/alfresco-opencmis-extension/">this page</a>. But maybe you've got a reason that I'm missing.

Also, something to think about: If you are using 4.2, you can now leverage CMIS 1.1 which means aspects are supported by the CMIS spec (referred to as "secondary types") which means you can work with aspects and aspect-defined properties without the extension.
