[Zope] objectValues return value

I wrote a script the returns a list object of all title_or_id values of objects in a folder. The problem is when there are no objects in the folder. The script should return a list contianing the string 'none'.. but doesn't. In fact, the script seems to either hang or have no return value... Any pointers? # returns a python list contained the title of the page templates in this folder list = context.objectValues('Page Template') if list == None: return ['none'] newlist = [] for zpt in list: newlist.append(zpt.title_or_id()) return newlist -- David Bear College of Public Programs/ASU Mail Code 0803
