    Shared nodes and Versioning

    Brian Wallis Master

      I seem to have found a problem when using shared nodes in a tree with mix:versionable on the root node. The CND i'm using is:

       

      {code}

      [A] > mix:versionable

        - name (string) copy

        + b (B) multiple copy

        + c (C) multiple copy

       

      [B]

        - name (string) copy

        + c (C) multiple copy

       

      [C] > mix:shareable

        - name (string) copy

      {code}

       

      When I run the following bit of code (I'll include the full code as an attachment) with an existing simple tree of nodes that is /a/b/c I get a ConstraintViolationException.

       

      {code}

      71:  versionManager.checkout(a.getPath());

      72:  workspace.clone(workspace.getName(), c.getPath(), "/a/c", false);

      73:  versionManager.checkin(a.getPath());

      {code}

       

      The code is trying to clone the node at /a/b/c to /a/c which should create a shared node that is at both /a/b/c and at /a/c. The clone operation works fine but I get the exception at the line that does the checkin.

       

      The error is:

       

      {code}

      javax.jcr.nodetype.ConstraintViolationException: Cannot find a definition for the child node named 'c' on the node at '/a' with primary type 'A' and mixin types: []

      {code}

       

      If I change the type of the child node c in node A to "nt:base" then the error goes away and it works as expected.

      ie:

       

      {code}

      [A] > mix:versionable

        - name (string) copy

        + b (B) multiple copy

        + c (nt:base) multiple copy

      {code}
