How to switch to editable mode to a event after TimeRangeSelected Fired

There is no easy way to do it now because you can't pass custom data back with the callback result (you will need to pass new event id after adding it, then activating event edit on the client side).

However, it's planned for 4.1 ("Sending custom data back after callback/postback").

Sending custom data back with the callback result is now available in 4.1 but there is one more thing necessary - to be able to switch the event box into edit mode (when you know just the event id). I would like to add this option in 4.2.
