[Zope] How to hook __before_publishing_traverse__

[Sidnei da Silva]

Reading the documentation, i found out why i could not set permissions on the 
before_publishing_traverse. It seems that at this point, getting 
SecurityGetUser its not reliable.

So, i was thinking of a way to test for if a role is valid to access an 
object. Maybe Security.validate() or something, i dont know. And if theres a 
hook for testing when a property is accessed, like testing for some condition 
before returning title_or_id. Something like __before_property_access__.

Thanx.
