Smart Dashboard Preferences Issue

[jagow100]

We have found that when you follow the code here on Screensteps: http://wpilib.screenstepslive.com/s/...smartdashboard you get a null pointer exception. When you initialize the Preference object, you receive a not visible error, we're assuming this is because the constructor for preferences is private. How do we get this to work?

You need a line like:

Preferences* prefs = Preferences::GetInstance();

or

Preferences prefs = Preferences.getInstance();

depending on the language.
