Modern proper calendar control

in france week number is widely use, in public heath like below, and all legal stuff.semaine means week.

@Jeremie_L , Hello Jeremie, I try to run the calendar view on the latest XOJO version and it seems that I cannot run it. it fails complaining that

MainPage.ColorSelectorFilter.Shown
ColorSelectorFilter on MainPage implements the event “Shown,” but its superclass WebColorSelector has already implemented the event.
MainPage

When I try to edit that I discovered that most of the classes and encrypted so the project cannot be really used.

Is there a way to remove the encryption so we can update it ? it applies to both, desktop and web versions

Thanks
