[ZPatterns] Can't set proxy roles for SkinScript

[Itai Tavor]

Hi,

In Zope 2.5.1 with ZPatterns 0.4.3p2 (TransactionAgents 5), trying to 
set the Manager proxy role on a SkinScript results in:

    You are not authorized to change ... because you do not have proxy 
roles.

I thought we left this kind of nonsense behind a long time ago. What's 
happening?

Also, in a SkinScript that catalogs changed objects, I tried to avoid 
the need for the proxy role by giving my user role the "Manage ZCatalog 
Entries" permission, which is the one protecting uncatalog_object in 
ZCatalog, but I still get an access error on uncatalog_object in:

WHEN OBJECT CHANGED CALL
   Catalog.uncatalog_object(_.string.join(self.getPhysicalPath(),'/')),
   Catalog.catalog_object(self, 
_.string.join(self.getPhysicalPath(),'/'))

Can anyone think of a reason why the permission settings are being 
ignored?

TIA, Itai
