Hi,

I'm working on a special case, combining Arduino loaded with Firmata with processing.

I use two windows, one invoked from the normal Main script, and one from a public class called UIWindow. PShape works fine in the Main script, but in UIWindow it gets a nullpointerException.

Main script (simplified)

1. PShape oogSVG;
2. void setup() {
    
     size(1280, 1024);
    
     // Passing in this applet allows you to call functions in the parent
     uiWindow = new UIWindow( this, 1440, 900 );
    
     frame.setLocation(0,0);
    
    
   
     oogSVG = loadShape ("oog1.svg");
     smooth();
3. void draw() {
   
     // background(backgroundIMG);
     background(200);
   
     noFill();
     shape(oogSVG, 0, 0); }

UIWindow script

1. public class UIWindow extends PApplet
   {
   
     Frame frame;
     int width;
     int height;
     Arduino arduino;
     PShape infoSVG;
     Main parent;
   
   
     UIWindow ( Main _parent, int w, int h )
     {
       parent = _parent;
       arduino = parent.getArduinoClass();
       width = w;
       height = h;
       frame = new Frame( );
       frame.setBounds( 0, 0, width, height );
       frame.removeNotify();
       frame.setUndecorated(true);
       frame.setLocation( 0, 0 );
       frame.add( this);
       this.init( );
       frame.show( );
     }
   
     void setup( )
     {
       size( width, height, P2D );
       frameRate( 10 );
   
      infoSVG = loadShape ("kader1.svg");
   
     }
   
     void draw ( )
     {
     shape(infoSVG, 0, 0);
   }

This however doesn't work. It gives NullPointerException at InfoSVG = loadshape ("kader1.svg"); within the UIWindow class.

im not sure what i'm doing wrong here, but right now as far as code goes I feel like I'm solo-skydiving without training.
Anyone
