[Zope-dev] zpatterns-0.4: creating an item in "virtual mode"

[Jephte CLAIN]

Hello,

I use virtual attribute access to provide access to my SQL database.
However, I want to use the Rack.newItem facility to create new records
in the database.
But it fails because in virtual mode, an item always exists.
This patch solves the problem, at least for me
