[Zope-dev] possible bug in dtml-in

[Federico Di Gregorio]

hi *,

an external method returns a list of tuples like this one:

	[(elt1, elt2), (elt3, elt4), ...]

and i want to print something after the last one so i do:

	<dtml-in "build_list(args...)">
          ...do some work here...
          <dtml-if sequence-last>
            should be executed only after last iteration
          </dtml-if>
        </dtml-in>

that always worked (when getting stuff out of a DB, for example) but
with a list built as above, if there is *more* than 1 element i get...

any idea?

  Those who do not study Lisp are doomed to reimplement it. Poorly.
