Subject Re: Restore a version of a node property
Date Wed, 05 Apr 2006 10:07:20 GMT
you need to checkin first:

node = session.getRootNode().addNode("entry");
node.addMixin("mix:versionable");
node.setProperty("content", "1");
node.getSession.save();
node.checkin()   <---------------------

node.checkout();
node.setProperty("content", "2");
node.save();
node.checkin();
