[Zope-CMF] Add content programmatically

[Kevin Teague]

What you want to do is perform actions like automatically adding default 
objects to a new folder after the object has been initialized and stored 
in the Zope Object Database.

At the point that __init__ is called, the object is just residing in 
memory, and isn't yet 'set' into the databse. This means that anything 
that relies on acquisition won't work (like the invokeFactory method). 
What you might want to do is call invokeFactory in your 
manage_addCMFExtNews method, after something like "self._setObject(id, 
ob)" has been called.
