Subject [jira] Created: (JCR-1792) jcr:frozenUuid does not contain jcr:content
Date Tue, 07 Oct 2008 17:00:44 GMT
jcr:frozenUuid does not contain jcr:content
-------------------------------------------

                 Key: JCR-1792
                 URL: https://issues.apache.org/jira/browse/JCR-1792
             Project: Jackrabbit
          Issue Type: Bug
          Components: jackrabbit-core
    Affects Versions: core 1.4.5
         Environment: tomcat, jackrabbit deployed inside webapp, xml persistance, webdav enabled
            Reporter: Nicholas DiPiazza


When I store versionable files, I get problems retrieving the jcr:data from a custom node
type.

I am storing a node type:

xrc:learningContent
        pd: xrc:Keywords
        pd: xrc:MimeType
        pd: jcr:mixinTypes
        pd: xrc:Description
        pd: xrc:Language
        pd: xrc:Creator
        pd: jcr:created
        pd: xrc:Title
        pd: jcr:primaryType
Extends: nt:resource
        pd: jcr:uuid
        pd: jcr:mixinTypes
        pd: jcr:data
        pd: jcr:encoding
        pd: jcr:mimeType
        pd: jcr:lastModified
        pd: jcr:primaryType

So I commit the changes, then later pull up the version and get it's frozenNode.

Node frozenNode = v.getNode(JcrConstants.JCR_FROZENNODE);

And then I return all of the properties contained within:

PropertyIterator pi = frozenNode.getProperties();
                while (pi.hasNext()) {
                    System.out.println(pi.nextProperty().getName());
}


All that are returned are:

jcr:frozenUuid
jcr:uuid
jcr:frozenPrimaryType
jcr:frozenMixinTypes
jcr:primaryType

Here is the frozen node type:

nt:frozenNode
        pd: *
        pd: *
        pd: jcr:frozenUuid
        pd: jcr:uuid
        pd: jcr:mixinTypes
        pd: jcr:frozenPrimaryType
        pd: jcr:frozenMixinTypes
        pd: jcr:primaryType



So basically it would seem that the recursive copy inside the InternalFrozenNodeImpl is not
working. But it seems that is not the case from the code trace I did. Add this to line 368
of InternalFrozenNodeImpl.java

System.out.println("New node created. Props: ");
        try {
            PropertyState [] ps = node.getProperties();
            for (PropertyState p : ps) {
                System.out.println(p.getName());
                System.out.println(p.toString());
            }
            NodeStateEx [] ns = node.getChildNodes();
            for (NodeStateEx n : ns) {
                System.out.println(n.getName());
                System.out.println(n.toString());
            }
        } catch (ItemStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


And you will get the result:

So the new Node definately has these new properties.

Do I have to somehow extend my frozenNode to work with this? Can anyone help me?
