We have a CMS application (Jackrabbit 2.2.0) that uses mix:versionable
nodes in the draft workspace but then tries to strip the mix-in when
promoting to the next workspace in the workflow.  For code like the
following:

=20

1              if (node.isNodeType("mix:versionable")) {

2                              node.removeMixin("mix:versionable");

3              }

=20

Even when the check in line 1 passes, we still get the following
exception at line 2:

=20

Caused by: javax.jcr.nodetype.NoSuchNodeTypeException: Mixin
mix:versionable not included in node /a/b/c

Any ideas?  Thanks -
