Re: Removing root version

[Brian Thompson]

Are you checking out the document node before you check on its version
history?  If not, that might cause the problem.

Also, if you're removing the document node, you probably have to check out
its parent.

I would like to implement rollback function for the versioned node. If

of the node, the root (top, head) node is removed. I tried v.remove() or
history.removeVersion(v.getName()), but both fail with exception:

javax.jcr.nodetype.ConstraintViolationException:

Here is the code:

            VersionHistory history = document.getVersionHistory();
            VersionIterator ito = history.getAllVersions();
            if (ito.hasNext()) {
                Version v = ito.nextVersion(); // Top version
                if (ito.hasNext())
                    v.remove();
                else
                    document.remove();
                session.save();
            }


My question is, is it possible or do I have to use workaround like create
new version from version head-1 (create new version) and then remove the
original root version and the original head-1 version?
