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.

Thanks for your help.
