Re: [Zope] sequence-item and ""
I've patched this for 2.1.6. Now you can use sequence_item in addition to sequence-item. http://www.zope.org/Members/jfarr/Patches/dtml-in-sv There's a much cooler and more elegant solution in the pipe for 2.2. http://www.zope.org/Members/4am/DTMLWiki/NamedDTMLInLoop --jfarr "Perl is worse than Python because people wanted it worse."

I've searched through the list archives and come to the conclusion that your solution above is the cleanest way to handle this, for now. There are other ways, but they involve ugly-looking permutations of the "_" namespace variable, and they approach the splendor of Perl in their readability. The "right" solution, IMHO, would be to rename the "sequence-..." variables to a different set of names that doesn't cause the Python interpreter to choke. I seem to recall someone saying that this (or something similar) was being worked on, but, alas, for now is our best option. rob > > Can anyone help me? > > - > Diego Rodrigo Neufert > -webmaster > --- > (Magic Web Design) > (email) ([EMAIL PROTECTED]) > (curitiba) (pr) > > ___ > Zope maillist - [EMAIL PROTECTED] > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) > ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
