[TimMoore]

The user is actually created: the issue is just that an error appears on the next page. If you reload the page after 10 seconds (the eventual consistency delay) then it loads successfully.

[TimMoore]

I think I understand the problem: the user repository is eventually consistent. This page assumes the user will be available immediately. This is related to the change in #143, but I think we want to take a different approach, and make a userService.getUser(id) call to retrieve the details for the currently logged-in user.

Fixed by #143
