PShape not drawing

Hi, I'm using a Windows 7 machine and Processing 2.0b8 and I'm simply trying to draw a PShape that will translate across the screen but the line is not showing up.  Anybody see the problem?

private PShape shape;

private boolean left = false;

private int count = 0;

public void setup() {
  size(1280, 720, P2D);
  this.shape = createShape();
  this.shape.beginShape();
  this.shape.vertex(width / 2, 0);
  this.shape.vertex(width / 2, height);
  this.shape.endShape();
  this.shape.setStroke(0);
  this.shape.setStrokeWeight(10);
}

public void draw() {
  background(255);

  if (left)
    this.shape.translate(1, 0);
  else
    this.shape.translate(-1, 0);
  count++;
  if (count == width) {
    this.left = !this.left;
    this.count = 0;
  }
  shape(this.shape);
  
  System.out.println(this.shape.getVertexX(0));
}
