[Zope] Need more enlightenment on traverse hook and security

Hi, Thank you, Toby Dickenson and Dieter Maurer, for your tips on my problem. It's cracked instantly! However, as a layman of python and Zope, I couldn't figure out the meaning of "MyObj(name).__of__(self)". What is '__of__' funtion? I can dig very little information about '__of__' from python's website. What's the difference between 'Acquisition.Implicit' and 'Acquisition.Explicit'? And why these two steps are required to solve my problem? Look forward to your enlightenment. Cheers Dirksen __________________________________________________ Do You Yahoo!?
