Dear Zope Users, Fairly new to Zope, but I am writing a Python Script. I would like to use exceptions in my processing flow, but the security restrictions won't allow it. What is the recommended approach here? For example, what I would like to do, but am not allowed to, is: # sample_py ---------------------------------------- request = container.REQUEST RESPONSE = request.RESPONSE try: username = request.get("username", None) if len(username)==0: raise "ZeroLengthUserName", None except: import sys # SECURITY won't allow print sys.exc_type; return printed # process username here... # return another dtml document/method return context.registered_ok_dtml(context,context.REQUEST) # end sample_py ---------------------------------------- Thanks, Roy Mathew. ps: please respond directly to me as well, if you could.
