PShape method issues (update: resolved)

EDIT: RESOLVED (version issue - see below)

Hi all - running processing 2.0b3 and seem to be having issues calling the set methods. I keep getting errors that look like: "The method setStroke(int, int) in the type PShape is not applicable for the arguments (int)"

1. 1. PShape rectangle;
   2.  
   3. void setup() {
   4.   size(640,360,P2D);
   5.   rectangle = createShape(RECT,-50,-25,100,50);
   6.   rectangle.setStroke(color(255)); 
   7.   rectangle.setStrokeWeight(4);
   8.   rectangle.setFill(color(127));
   9. }
