Adding captures to array

Hi guys,

I'm trying to collect captures from the webcam to an array of PImages, but it seems like all images in the array are the same one. This is the relevant code. Any ideas on how to I get around this?

Capture cam;
boolean activate = false;
ArrayList<PImage> imagesSoFar;
int currentIndex = 0;
int framesNumber = 50;
PImage imageToAdd;
public void setup(){
size(900,600);
String[] cameras = Capture.list();
cam = new Capture(this, cameras[0]);
cam.start();
imagesSoFar = new ArrayList < PImage >();
}
public void draw(){
if (cam.available()) {
cam.read();
}
image(cam,0, 0,width, height);
if(activate){
if (currentIndex == 0){
}
if(currentIndex<framesNumber){
imagesSoFar.add(cam);
currentIndex ++;
}

Changed topic type to question.
Moved to core library questions.

Your code is not runnable because it is misses brackets and imports. Looking at the code I think the problem is in line 24. You are adding a reference to the Capture object instead of a PImage. This doesn't throw an error because the Capture object probably extends PImage. To solve this try using:

imagesSoFar.add(cam.get());
