    }

    public void whenInactive(Command command){

        System.out.println("meh3");

    }

}

this displays the button on the dash but wont do anything when clicked...

still getting above error

That's not how you use it.

Code:

Trigger doThingyTrigger;

doThingyTrigger.whenActive(new DoThingy()); // DoThingy is some class extending Command

SmartDashboard.putData("Do Thingy",trigger);

I'd put this in robotInit, but it can be almost anywhere.

I get the above error when trying to use the Prefrences class... other stuff was just blabble

Just found the error that you are showing here. It is a bug in the Preferences class in WPILib. There is a fixed version of it in Stable (not Release) release of WPILibJ. Can you try updating your plugins to the Stable version by editing the plugin location and changing "Release" to "Stable" in the URL? Let me know if it work for you.

Also, there is an example of using the Preferences class here:
