[Zope] Confused about new permissions in ZClasses

[Kevin Dangoor]

Hi,

    I'm working with some ZClasses in 2.0b1 and I am confused about the
new permissions setup.

    Using the clean Data.fs file, I created a new Product. Then I
created a ZClass that inherits from Object Manager. If I go into the
ZClass and select the "Permissions" tab, and I see a familiar set of
permissions listed as "Inherited permissions":

Access contents information
                              Change permissions
                              Delete objects
                              FTP access
                              Import/Export objects
                              Manage properties
                              Undo changes
                              View
                              View management screens

Then, I click on the Define Permissions tab. If I click the "Access
contents information" drop down menu, it looks like everything *except*
the inherited permissions is listed. Shouldn't I be able to select the
"Access contents information" permission?

Also rather interesting is that if I create another ZClass on the
Methods tab of the first one (also inheriting from Object Manager), then
go into that ZClass, click the Define Permissions tab. Now, I can select
"Access contents information" for that permission. But, if I try to
actually save the changes, I get an error ("Waaa", in fact:) :

Traceback (innermost last):

waaa

There must be something fundamental I'm missing here...

Thanks,
