Hi I try to run ZFSPath example http://zope.org/Members/asterisk/ZFSPath but it is telling me "This resource may be trying to reference a nonexistent object or variable 'listdir'." I did following steps 1) Create a ZFSPath object in my folder 2) name ID as darkforest 3) In ZFSPath Properties I put a path "/darkforest " and title "Share file system" 4) I try to run the following Zope Page Template (ZPT) <html> <head> <title tal:content="template/title">file share </title> </head> <body> <h2 tal:content="here/darkforest">path</h2> <div tal:define="contents here/listdir"> <p><a href="..">..</a></p> <p tal:repeat="element contents"> <a href="#" tal:content="element/darkforest" tal:attributes="href element/darkforest">file</a> </p> </div> </body> </html> any idea what is wrong ? thx Frasse
