Hi, I'm new, so i hope this is the appropriate place. When running through the example in Ch 12 of the Zope Book (http://www.zope.org/Members/michel/ZB/CustomZopeObjects.dtml) all is well until i add the Python Script to the add object. I get the following error (the script is at the end of this note). Any thoughts? Thanks, mark PS-it has happened on two different Windows machines. ____________________________ Error Type: KeyError Error Value: parameters: id ,title, request Traceback (innermost last): File C:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 223, in publish_module File C:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\Program Files\Zope\lib\python\Zope\__init__.py, line 226, in zpublisher_exception_hook (Object: add) File C:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\Program Files\Zope\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: ZPythonScriptHTML_editAction) File C:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: ZPythonScriptHTML_editAction) File C:\Program Files\Zope\lib\python\Products\PythonScripts\PythonScript.py, line 197, in ZPythonScriptHTML_editAction (Object: add) File C:\Program Files\Zope\lib\python\Products\PythonScripts\PythonScript.py, line 216, in ZPythonScript_edit (Object: add) File C:\Program Files\Zope\lib\python\Products\PythonScripts\PythonScript.py, line 451, in write (Object: add) KeyError: (see above) _____________________________ ## Script (Python) "add" ##parameters: id ,title, REQUEST=None ## """ Copy the exhibit template to the calling folder """ # Clone the template, giving it the new ID.
