Re: Pier permissions problem - smallwiki

31 May 2007

...
  Having added a subclass of PRPage, I cant add one in
pier due to a  
 permissions error. 
If you are logged in as administrator this should work.

...
  Now I understand that an existing page's
permissions would not be  
 aware of the new class. So I added a new PRPage first, then  
 attempted to add the new page type to that. Still no go. So I set a  
 halt in PUSecurity-validateCommand: to investigate further.

 It appears that the ownerPermissions set is being created with nils  
 in the first couple of slots. This results in #includes: returning  
 false before it finds the PUAddPermission that it is looking for in  
 slot 4  (in this instance). 
The permissions (Unix Security) of new pages inherit from their  
parent. Since no structure knows about the 'add new xxx permission'  
this won't give you that permission either. You have to explicitly  
add this permission using the security commands to have it useable  
from a non-admin user.

...
  The code in the above repository simply converts the
sets to arrays  
 before the #includes: test and all is fine. 
I don't understand how this could help?
