This sketch produces NullPointerException when loading the chart controller:

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system? 0.5.4 in Snow leopard

The Sketch demostrating bug:

//################ import controlP5.*; ControlP5 controlP5; Chart myChart;

void setup() { size(600, 400); controlP5 = new ControlP5(this); myChart = controlP5.addChart("Hello", 20, 20, 400, 100); }

void draw() { background(0); }

void keyPressed() { if (key=='s') { controlP5.save(); } if (key=='l') { controlP5.load("controlP5.xml"); } } //################

Hi, save-to and load-from an xml file has been removed with later than 0.6.0 versions of controlp5 and has been replace with the implementation of ControllerProperties.
