That's a nasty side effect of the caching performed by
many DTML tags:

  If you use "<dtml-if name=XXX ...>" (this is the explicit
  form of "<dtml-if XXX ...>"),
  then "XXX" is rendered and bound to the name "XXX".
  When you later access "XXX", you get the already rendered
  value.

  If "XXX" is (originally) bound to a DTML object (as in your case),
  then it is very likely that its rendered value is a string
  which (of course) does not have an "absolute_url" method.
