In 'normal' Silva I presume this also works? However it's going to a 
nested myDoc, as in 
http://localhost:8084/silva/ETH/myDoc/myDoc/edit/preview_open_now
But it still works.

Might the fact that it's a form submission have something to do with it? 
Somehow, when the form submits, you're not 'in' your doc, but the 
container above.
