Right now, when an user uses a form to create a new document and then cancels his action, he is presented with a message saying "This document does not exist". Let's take the following example:
- User goes to the Blog.WebHome page
- User inputs a post title and clicks on create
- User clicks on cancel
- The user is presented with a page saying "This document doesn't exist"
-> the user should be sent back to the page where he came from instead of being left on an unhelpful page.
