[Zope3-Users] __setitem__ works, __delitem__ fails on custom site

[Roy Mathew]

Thanks, David - that did the trick. 

I changed the decl:
  class IQSite(IPossibleSite):
to:
  class IQSite(IFolder):

and had to remove the IWriteContainer and IReadContainer perm decls to
avoid a conflict.

I am still not sure why that would make the difference - since QSite
extended Folder to begin with, wasn't it also of type IFolder?

Roy.
