    SNS problem

    Brian Wallis Master

      This is a question about a problem I've been staring at and playing with for many long hours now. It should be simple and just work but I am obviously missing something. I have had the code in question running before (probably with a beta of 3.0) but it might have changed a little since then. I'm currently running the code in jboss EAP6.1 alpha and with a recent modeshape snapshot of 3.2. I also tried it with boss 7.1.1 and 3.1.3 modeshape with the same results.



      I just cannot see what I am doing wrong here.  I don't have a simple test case (tried to create one but it works ok!)


      Any suggestions if you can see something I am doing wrong here would be greatly appreciated.


      I have the following snipit of code


      {code}                              Node newNode = new JaxbNodeTransformer().includeProperties(true).includeSubnodes(true).includeMixins(true).toJcrNode(parentNode, nodeDef);


                                    log.debug("Created Node "+newNode.getIdentifier()+" path="+newNode.getPath()

                                                        +" in parent node "+parentNode.getIdentifier()+" path="+parentNode.getPath());

                                    log.debug(" Parent Node type="+parentNode.getPrimaryNodeType());

                                    log.debug(" This Node type="+newNode.getPrimaryNodeType());

                                    log.debug(" This node allows SNS Sibs = "+newNode.getDefinition().allowsSameNameSiblings());

                                    log.debug(" This node name = "+newNode.getDefinition().getName());







      The newNode creation is buried inside some xml processing but just calls addNode on the node passed in as parentNode (which is of type inf:patient). The part of the schema used is



      {code}[inf:patient] > mix:versionable, nt:hierarchyNode

                + * (inf:patientId) COPY

                + * (inf:section) SNS COPY

                - inf:masterId (STRING) mandatory COPY

                - inf:masterNs (STRING) mandatory COPY




      * A section node is a named container of either episodes or documents.


      [inf:section] > nt:hierarchyNode orderable

                - inf:name (STRING) mandatory COPY

                + * (nt:hierarchyNode) SNS VERSION




      and I get the following output which looks like what I expect, particularly bit about the SNS sibs being true.

      but when the session.save() is called I get an error where it complains about not allowing SNS siblings

      I am stumped by this.

        • 1. Re: SNS problem
          Randall Hauch Master

          I've successfully created a standalone test case that replicates the situation:


          - create an inf:patient node (with any mandatory properties)

          - create one or more inf:section nodes (with any mandatory properties)

          - save

          - create another inf:section node (with any mandatory properties) <-- causes ItemExistsException


          Note that the "inf:patient" node definition must have two residual child node definitions (one of type "inf:patientId" and the other of "inf:section") in order for this test to fail. If the "inf:patientId" child node definition is removed, then it works fine.


          I've logged this as MODE-1878, and am testing a fix.

            I've corrected the problem on 'master'. Please let me know if this does not fix your problem, and we can reopen the issue.

              Thanks Randall,

                 I rebuilt 3.2 from master, reinstalled into jboss EAP and that has fixed the problem I was seeing.
