All the other users (Managers or not) can't. In normal usage, one only accesses a rack from or in a Specialist. Specialists wrap the objects in the context of the specialist for you. I've just checked the code, however, and notice that Specialist.__bobo_traverse__ does this wrapping, not Specialist.getItem, so I will fix this in the next release. That way, calling getItem on the Specialist will ensure you have proper context. Patch follows...

[Zope-dev] zpatterns: rackmountables must be of-wrapped
Hello, I believe items got from a rack have to be wrapped in context of the rack. I've been bitten by this (and it hurts!). When I try to use items from DTML, only the superuser can use it, even managers can't access the objects. When I wrap the items in the context of the rack, everything is fine. So: retrieveItem, createItem use vanilla objects getItem, newItem wrap objects before returning them regards, jephte clain [EMAIL PROTECTED] ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
