    Description

      I am not sure why it is crashing, see attached. It seems to be trying to size a NULL qlist. I think this comes from the sensor being active but it returning NULL readings? I am attempting to do:

      Accelerometer

      { active: parent.visible }

      also setting active in parent.onVisibleChanged: accel.active = visible
