Addforms aren't views for the thing they're adding. After all, the 
addform view is supposed to create the object for us in the first place. 
Addforms are views for adding views. Adding views are views for 
containers that are invoked when adding stuff to them.

   some_container/@@+

is usually the adding view for a container.  You can invoke add forms 
with the action.html view for the adding view:

   some_container/@@+/action.html?type_name=NameOfYourAddForm

(If you look closely at the Add menu in the Contents page of containers, 
you will see that all URLs are composed like this...)
