    Command canexecute not updating

    Basically it guesses all the possible events where your data could be changed.It can never know when your View Model/Model is changed.

    When I click my "Start" button (bound to 'Start Command'), the "Save" button is correctly disabled.But keyboard or mouse events are not the only things which causes invalidation I guess.If I'm not wrong, they are raised when window gets activated/deactivated etc.I have a problem regarding the state of a menuitem in Context Menu. The cars are visualized in a List Box, for each List Box Item I want a Context Menu.In that Context Menu there is an option Reserve Car.
