Subject: Jackrabbit 1.0 RC3 and references to versions
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Hi all,
  I have downloaded jackrabbit-1.0-rc3 and tested with my application. 
Almost everything works fine but i have discovered a problem with 
jcr:deref queries (yes I am "jcr:deref-boy"  :- )).
In my application there are several nodes that have a reference property 
to a version of a particular node (actually a reference to 
jcr:frozenNode). Prior to 1.0-rc3 version works fine, but with the last 
release a query searching for this nodes returns 0 results.
  I don't know if it is correct to use references to nodes in the 
version workspace or it is a problem of the Query Manager.

I have tested it with version 0.9-rc1-incubating and with some 
house-made versions and it worked well.

Here is a a JUnit method that tests this issue:


    public void testVersionDerefSearch() throws Exception {       
        Session currentSession = JCRUtil.currentSession();
        Node myRootNode = currentSession.getRootNode().addNode("root");
        currentSession.save();
        try {
            Node referenced = myRootNode.addNode("referenced");           
            referenced.addMixin("mix:versionable");
            currentSession.save();
            Version version = referenced.checkin();
            Node referencedVersionNode = version.getNode("jcr:frozenNode");
            Value referenceValue = 
currentSession.getValueFactory().createValue(referencedVersionNode);
            Node referencer  = myRootNode.addNode("referencer");
            referencer.setProperty("aReference",referenceValue);
            currentSession.save();
            String 
query="/"+myRootNode.getPath()+"/*[@aReference]/jcr:deref(@aReference,'*')";
            QueryManager qm = 
currentSession.getWorkspace().getQueryManager();
            Query q = qm.createQuery(query, Query.XPATH);
            QueryResult qr =  q.execute();
            NodeIterator ni = qr.getNodes();
            assertEquals("Must find one result in query",1,ni.getSize());
            while (ni.hasNext()) {
                Node node = (Node) ni.next();
                
assertTrue(node.getProperty("jcr:frozenUuid").getString().equals(referenced.getUUID()));
            }           
        } finally {
            myRootNode.remove();
        }
    }
