Getting Rotation to work with XBOX 360 controller

[TheLegion]

Hello all

So our team is programming in java and we are having trouble getting the robot to turn/rotate. We are using a XBOX Controller and using the left stick to go forward and strafe and the right stick for turning/rotation. The left stick functions perfectly but the right stick has issues. When the right stick is moved around, the robot starts to rotate but then will stop. It never completes a rotation fully. We are using mecanum. Here is our code so far:

while (isOperatorControl()&&isEnabled()) {
      double leftXAxis=xboxController.getRawAxis(1);
      double leftYAxis=xboxController.getRawAxis(2);

      chassis.mecanumDrive_Cartesian(leftXAxis, leftYAxis, xboxController.getRawAxis(4),0);

Basically my question is how to get rotation to work with the right stick.

Thanks
