@ZitaNemeckova This is giving a conflict on backport. node[0] to node.last change was in #379. PR 379 was backported via ManageIQ/manageiq#14227, but PR 14227 didn't include this node change, so I'm not sure if this was on purpose..

If this PR can go in as is, I'll resolve the conflict during backport. Let me know.
