[ZPatterns] access denied error

[Joachim Schmitz]

Hi Steve,

after some rest during the weekend, back to this issue.

I changed the storage-zclass for this specialist to an "old" zclasss, which
was created half a year ago with Zope 2.2, and the problem goes away !!!!!

To answer you question below, the objects are stored in ZClasse, with the
Base Classes:
ZObject, _ZClass_for_DataSkin

this is the same for "old" and "new" ZClasses.
