I'm having some troubles with manipulating the namespace of DTML methods that are called from methods of product instances. Some questions: - How do I provide a DTML method with a full acquisition namespace, as if it were called in DTML, when I call it from a product class method? - Does a REQUEST.set(somevar, somevalue) operation add a variable to the namespace, or does it re-initialize a new request? I can hardly imagine the latter. - Does the local scope of a class method in a product somehow propagate itself to external DTML methods that are called from that class method? Context of my problem: My product has the following class: class NFGnav( OFS.SimpleItem.Item, Persistent, Acquisition.Implicit, AccessControl.Role.RoleManager ): which ultimately calls a DTML method: return self.NFGnav_ActiveMapItem(REQUEST) I can set arguments for the DTML method, no problem: REQUEST.set('NFGnav_ItemTitle', object.title_or_id()) before calling the DTML method works just fine. However, the DTML method seems to lose it's acquisition context in the process. That is, if I define an 'myimage' instance somewhere higher up in the site hierarchy, I get KeyErrors if I try to call <dtml-var myimage> from the DTML method. Funny thing is, if I request the URL of the product instance with the 'myimage' appended, this seems to have no problem: /mysite/somefolder/ProductInstance/myimage returns the image, whereas /mysite/somefolder/ProductInstance/someMethod/myimage gives a KeyError. So the aquisition context seems to be intact at the product class level, but not at the product class method level. I took care to provide (PARENTS, REQUEST) parameters for every class method invocation, by the way. I'd appreciate any suggestions in tackling this problem. Is this question more suited for the zope list or for the zope-dev list, by the way? Source for the product is available at http://www.zope.org/Members/gyst/NFGnav :*CU# -- *** Guido A.J.
