Yeah, but this is not the answer I was looking for. This checks for any parent
and I need to check only for the parent at the root.
example:
  I have folders:
  /test/blah/qwer/wert/erty/rtyu/
  /test/ouch/asdf/sdfg/dfgh/fghj/

  so when i execute a script from /test/blah/qwer/wert/erty/rtyu/ i
  get a list of subfolders in /test/, that's "blah" and "ouch" and then i
  must determine which one of the two is my parent. Your model would
  not work in a case when any other parent of the current folder has
  also id of blah which could happen on my site :)

I have partially solved my problem. I'm comparing a list of /test/
subfolders with "PARENTS[-3].id" and it works just fine but thing
blows up when I try to execute script from /test/ and it's easy to
understand why because in /test/ "PARENTS[-3].id" does not exist.
My problem now is only to check if "PARENTS[-3].id" exists but how can
I do that? <dtml-if "PARENTS[-3].id"> for some strange reason does not
work :(
