I have recently tried to upgrade to p5 v148.
I'm currently working on a library using OpenGL. Everything was working fine with p5
v135. It seems to be when post() inside a library is calling something to draw in the
PApplet.

Otherwise, here's a link to someone who had a same error code, but doesn't seems
to be the same error.

[code]public class MyLib {

final public PApplet p5;

public MyLib(PApplet p5){
this.p5 = p5;
p5.registerPre(this);
p5.registerPost(this);
}

public void pre(){
p5.emissive(1);
p5.shininess(1);
p5.directionalLight(75,75,35, -1, -1, -1);
}

public void post(){
p5.stroke(255,0,0);
p5.line(0,0,p5.width,p5.height);
}

}
[/code]

from libraries/howto.txt:

public void post()
method called after draw has completed and the frame is done.
no drawing allowed.

Thx!

I was using post() instead of draw() because I unsure if draw was called after
PApplet.draw(). It was working for a while.

Thank you, Thank you, everything is working now.
