Shared nodes and Versioning

[bwallis42]

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}

That does seem like we're not finding the appropriate child node definition on 'A'. Can you log an issue? Looks like we'll probably have a 2.8.1 release.
