Zope's permission machinery works only with "acquisition wrapped" objects.

to learn more about acquisition wrappers.


In Zope objects are usually automatically wrapped during traversal
or attribute lookup.

In your own product, several thing can prevent wrapping:

 * in the constructur, the object being constructed is
   not yet wrapped

 * the class must be derived (directly or indirectly)
   from "ExtensionClass.Base".
