Hi ppl... Why I cant use dtml-var "sequence-item">?? Every time I try to access sequence-item under "" in a dtml-call dtml-var or anything else I got this error: Error Type: NameError Error Value: sequence Well, I found a solution: <dtml-let si=sequence-item> <dtml-var "si"> </dtml-let> Now everything is ok... but I dont want to do this, I want to access the *&@%$#@& sequence-item in "".

Because anything inside quotes is evaluated as a Python expression. It's trying to subtract 'item' from 'sequence.' Try: <dtml-var "_['sequence-item']"> -CJ

Because, as I understand it, anything within "" gets treated as Python code by the DTML interpreter. Thus "sequence-item" is parsed as an expression: sequence _minus_ item. A dash is not a valid variable name character in Python, but it is in DTML; this is unfortunate.

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 <dtml-let> is our best option. rob

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 don't think this landed for 2.2... Chris
