[Zope] Newbie Q:<dtml-with> and the PARENTS tag

[Ausum]

Your code is right:
 <dtml-with "PARENTS[0]" only>
      <dtml-if PropertyX>
       <dtml-var PropertyX>
       .....do some stuff...
      <dtml-else>
       .... something else
     </dtml-if>
 </dtml-with>

The only thing to consider is that Propertyx must be at every folder at
wich Method1 will work, no matter it has a value or not. Of course, if
it had a value, it will show off. If not, Zope will trigger the else
condition without looking downward.
