I ran into an issue when attempting to lock nodes using public users session,
see sample code snippet bellow:
[code]Session session =
MgnlContext.getJCRSession(CommonConstants.Repositories.DAM);
Node root = session.getRootNode();
Node test = JcrUtils.getOrAddNode(root, "test1",
CommonConstants.NodeTypes.FOLDER);
test.addMixin("mix:lockable");
session.save();
LockManager lock = session.getWorkspace().getLockManager();
lock.lock(test.getPath(), false, true, 5000,
MgnlContext.getUser().getIdentifier());
Node test2 = JcrUtils.getOrAddNode(root, "test2",
CommonConstants.NodeTypes.FOLDER);
session.save();
session.getWorkspace().getLockManager().unlock(test.getPath());[/code]
Running this snippet will blow up with this error:
[code]

However if i execute same code as a superuser:
[code]return MgnlContext.doInSystemContext(new
JCRSessionOp<Node>(CommonConstants.Repositories.DAM) {
@Override
public Node exec(Session session) throws RepositoryException {
//Session session =
MgnlContext.getJCRSession(CommonConstants.Repositories.DAM);
Node root = session.getRootNode();
Node test = JcrUtils.getOrAddNode(root, "test1",
CommonConstants.NodeTypes.FOLDER);
test.addMixin("mix:lockable");
session.save();
LockManager lock = session.getWorkspace().getLockManager();
lock.lock(test.getPath(), false, true, 5000,
MgnlContext.getUser().getIdentifier());
Node test2 = JcrUtils.getOrAddNode(root, "test2",
CommonConstants.NodeTypes.FOLDER);
session.save();
session.getWorkspace().getLockManager().unlock(test.getPath());
return test2;
}
});[/code]
It works perfectly, however this is not ideal as this approach ignores the
access permissions per user...
Do you have to be superuser to perform node locks ?
