NetBeans CommandBasedRobotTemplate
 

I think there is a bug in the NetBeans CommandBasedRobotTemplateProject...

In the init() method of CommandBase.java it creates an instance of OI as shown below:

public static void init() {
// This MUST be here. If the OI creates Commands (which it very likely
// will), constructing it during the construction of CommandBase (from
// which commands extend), subsystems are not guaranteed to be
// yet. Thus, their requires() statements may grab null pointers. Bad
// news. Don't move it.
oi = new OI();

It should be using the static singleton instance:

oi = OI.getInstance();

The constructor for OI should also be private. As it stands now, if you access the static instance elsewhere, such as:

m_drive.arcadeDrive(OI.getInstance().getJoystick() );

you will have 2 instances of OI floating around.
