Patch "doubloon-on-node-type-human-names-2396141-3.patch" does display the error message for unique machine-readable name and not for human-readable name. However, when user tries to enter an unique name on the same page and save the field, the error message does not disappear. So, this patch fails. Attaching screenshot.
