Alright, what's the trick to be able to retrieve the URL of a Zope object via DTML whose id has blanks or punctuation in it? For example, in a normally-named object called 'site_css', I'd do:
Ex. 1 <LINK REL=stylesheet HREF=<dtml-var "site_css.absolute_url()"> TYPE="text/css">
<LINK REL=stylesheet HREF="<dtml-var "_.getitem('site.css', 0).absolute_url()">" TYPE="text/css">
This retrieves the object from the namespace without calling it.
Thanks Martijn -- that works fine! At the risk of sounding dumb, I don't quite understand it -- why does the 0th array element within object 'site.css' contain a pointer to the object itself and how would a Zope developer know this? I've been thru the Zope source and haven't come upon that particular construct. And naturally, what resides at other offsets?
