> I keep getting confused how to check the result of
> {{ResourceUtil.getParent(String)}} for the root path.
> https://sling.apache.org/apidocs/sling9/org/apache/sling/api/resource/ResourceUtil.html#getParent-java.lang.String-
> gives two reasons for the return value being null.
> https://sling.apache.org/apidocs/sling9/org/apache/sling/api/resource/ResourceUtil.html#getParent-java.lang.String-
> gives only one reason, but I suspect this in incorrect.
> so, FWIW, what is the return value for {{getParent("/")}}?
