[Zope] problems with manage_defined_roles

[Klaus Herrmann]

Hi!

I have problems with the manage_defined_roles() command:
whenever i try to do 
manage_defined_roles('Delete Role', REQUEST)
or
manage_defined_roles('Add Role', REQUEST)
i get 
Error Type: NameError
Error Value: HelpSys
i included the full error message at the bottom of this mail.
btw, i did set the role / roles var before i called the function,
mostly as described in a beehive-e-book. i've looked at Role.py but
didn't find my mistake :-(

what's wrong?

thanks in advance!

bye,
	Klaus
