Thanks for the answer! That kind of code should be detected by Vala compiler as an error. What approach would you recommend to cast "Value?" to "Value" ? It's not that bad if it is not yet possible, but I would really like to build the whole projet with --enable-experimental-non-null ;) -- Guillaume Poirier-Morency <guillaumepoiriermore...@gmail.com>
