initialize() Method - Command Based

[Tedi]

Hey guys,
So I was reading the wpilib documentation on the initialize() method within a command and it stated that the initialize() method will run "immediately before the command is executed for the first time and every subsequent time it is started". Now when we tested with our robot, it seemed like the initialize() method would only run when the class was instantiated and not every time the command was started. Could anyone please tell me if the initialize() method is supposed to run every time the command is started or is it acting as it should.
Thanks
