In my example, I’m trying to set a parent category on a category that already has a child category. Naturally, I hit an error message. Despite this, the category selectors are updated as if my action was successful.
Navigating back to the topic list (through the previous button from my browser) and back to the category edition leads to a 404.
These navigation issues persist until I force a page refresh.
The interface shouldn’t be updated in real-time to reflect a change if that change didn’t work.
