Andrew Lahser wrote I am trying to set and get a cookie from a Zope product. Do I need to pass in the REQUEST to get at the cookies and the response? If the answer is yes, then why does the tree tag not have to pass in the REQUEST?

The tree tag is a tag, not a product instance. It's 'render' method gets the current namespace dictionary when called, and it looks up the value of 'REQUEST' and 'RESPONSE' from that.

tags behave differently to products...

Ok. So does it follow that the UserDB product gets its namespace dictionary from the validate method, and that User Folder products are therefore different from other products? Or is there a method that is passed the current namespace dictionary when a object is rendered as DTML or called from DTML? Does the __call__ method receive the current namespace in any way?

for further reading, look at lib/python/TreeDisplay/TreeTag.py

Thats like reading brail in the dark, but I will give it another shot. Drew
