[Zope] ModuleSecurityInfo and Product registerClass

I have a product that defines a manage_addMyselfForm which has the following security declaration: from AccessControl import ModuleSecurityInfo modulesecurity = ModuleSecurityInfo() modulesecurity.declareProtected('View management screens', 'manage_addMyselfForm') modulesecurity.apply(globals()) The function manage_addMyselfForm doesn't have a docstring, and when I try to actually add the product through the web, I get "Missing doc string". Is there a missing security declaration I need? Any help appreciated. Richard
