custom category properties invisible via NodeService

HiTo implement a thesaurus we have extended the type cm:category… <type name="cms:ThesaurusTerm"> <title>Thesaurus term</title> <parent>cm:category</parent> <properties> <property name="cms:scopeNote"> <tit

That's strange - the JCR API is using the NodeService to retrieve property values.

JCR namespaced properties will not be visible via NodeService as these are properties that are relevant only to the JCR layer.

Have you tried the NodeBrowser (available in the Web Client/Admin Console) ? It displays everything about a node.

Yup we thought it was a bit strange too!

Same result in NodeBrowser.

FYI this is a snippet of the code we are using to check the props:


   private void listAssociations(NodeRef nodeRef,int level) {
      
      StringBuffer indent = new StringBuffer();
      for(int i=0;i<2*level;i++) indent.append(' ');
      
      List<ChildAssociationRef> childAssocs = nodeService.getChildAssocs(nodeRef);
      for(ChildAssociationRef assoc : childAssocs) {
         System.out.print(indent.toString()+"+ "+assoc.getQName());
         System.out.println(" (type="+assoc.getTypeQName()+")");
         
         Map<QName, Serializable> properties = nodeService.getProperties(nodeRef);
         for(Map.Entry property : properties.entrySet()) {
            System.out.println(indent.toString()+"  -"+property.getKey().toString()+"= "+property.getValue());
         }
         Serializable property = nodeService.getProperty(nodeRef,CommonsContentModel.PROP_CMS_NAME);
         if(property != null)
            System.out.println(indent+"cms:name="+property.toString());
         
         listAssociations(assoc.getChildRef(),level+1);
      }
   }

note the explicit attempt to retrieve a property in our namespace - this never returns a vlue for a subtype of cm:category.

This happens both agains HEAD and 1.4 versions.

If I could sneak in here…

Have a look at the alf_node_properties table to see if the properties were actually persisted to the database. Then, just clarify that you don't see the properties persisted in the Node Browser.

When are you doing the JCR tests w.r.t. to the session lifecycle?
When are you doing the NodeService tests w.r.t. to the transaction lifecycle?

hi Derek

All good questions - the answer is altogether simpler, and is not a bug in Alfresco, you will be overjoyed to hear.

Thanks for your assistance
