[Zope] Yihaw on 2.2.1b1, boolean properties

I just tried installing a freshly downloaded copy of YihawDirectory.zexp into a relatively new 2.2.1b1, but in vain. <snip> Error Type: Permission mapping error Error Value: Attempted to map a permission to a permission, Add Yihaw Objects, that is not valid. This should never happen. (Waaa). <snip> I'm still looking for a way to get rid of the "checked" state of some boolean properties, i.e. "toplevel" or "highlight" and such. Once it is set, it sticks. -- o ( Wolfgang.Strobl@gmd.de (+49 2241) 14-2394 /\ * GMD mbH #include _`\ `_<=== Schloss Birlinghoven, <std.disclaimer> __(_)/_(_)___.-._ 53754 Sankt Augustin, Germany ________________
