[Zope-dev] External Method Return value?

[Chris McDonough]

Clayton,

in an external method named emReturnStuff:

def ReturnStuff(argument):
   if argument=="this list":
       return ['1', '2', '3']
   elif argument=="that":
       return ['4', '5', '6']
   else:
       return ['0']

in a DTML method named dtShowStuff:

<dtml-var standard_html_header>
<dtml-in "emReturnStuff('this')">
   <dtml-var sequence-item><br>
</dtml-in>
<dtml-var standard_html_footer>

calling dtShowStuff should show:
1
2
3

changing the argument within dtShowStuff should return different lists.

etc.

untested.,
