Andy - looking up 'this' in a dtml method or document won't work unless you expose it in your python product/tag definition. I'm talking about getting 'this' inside a dtml tag that I have defined myself (i.e. <dtml-foobar></dtml-foobar>). If you want 'this' available in dtml, write an external method and just return 'self' def this(self): return self -Brett

Finally woke up on this problem. Got this working by simply calling resolve_url upon the request object. But what I want is a result that changes depending upon the object. Let's face it, this can be acheived a whole lot easier by creating a method for the objects and calling that. So thats what Ive done and stayed away from using a dtml-tag.
