Hi all, I had a very stange experience with my Zope instance today. (Zope 2.6.0 (binary release, python 2.1, win32-x86), python 2.1.3, win32) When I added an empty method to my application container class, then refreshed my product, the access to subobjects was lost for a couple of roles. When, after that, I deleteted the method, refreshed product, and retry, access was back ! Whatever was the name or the content or the place in the module of the added method, same result ! Now, when I removed a method instead of adding one, no problem at all. So, I decided to code my method elsewhere, on a subobject, and refreshed product. No problem anymore. Why ? What the hell happened ? Did I miss something ? Is there a link between permission, role, and changing classes ? Please help me before I go mad... Sinclair
