OK, so the 'view' object set in page templates is not the object to call
for rendering the page.

All in all, I managed to render the '+' view by calling the 'template'
object and passing the 'view' as the instance parameter

>>> markup = template(instance=view)

instead of calling the 'view' directly with:

>>> markup = view()

This seems to be generic enough
