It fails if PARENTS[1] evaluates to false. <dtml-if "PARENTS[1]"><a href="<dtml-var "PARENTS[1].absolute_url()">">back</a></dtml-if> last lines of traceback: File /usr/local/src/Zope-2.0.0-src/lib/python/DocumentTemplate/DT_Util.py, line 321, in eval (Object: PARENTS[1]) File <string>, line 0, in ?
