Exceptions thrown after setting phase color

[JasperAppec]

Changing the phase of an event and then selecting another item throws some errors because of a missing selected item at a given moment.

[BarbzYHOOL]

Everytime you put a phasemask, and then select another line, it throws an error (4 errors in a row if you click "ok") and it's impossible to use phases at all o_0
This is an app-breaking issue
