Done: Issue #224 is logged
I found the solution: I had a type in the javascript source so the ajax interceptor didn't run. All solved now.
Great, thx for the info. How can I handle the reverse? If a user posts a form with a date, the date is a utc date, but it has the value the user enterd. Should I update all dates in the controller and convert them from the user's timezone to utc? That seems quite inefficient.
