hi, i'm trying to create two classes where the instances of one class are stored inside an array in an instance of the other class. somehow it just doesn't want to work. when i try to append a node or just to expand the array i get an error message but i have no idea why.
i'm new to processing and more familiar with the flash way of coding. please help – i'm close to loosing my sanity!  


here is the nasty code:

CircleMap team1;
Node member1;

void setup(){
 size(400,400);
 noLoop();
 team1 = new CircleMap("some team");
 member1 = new Node("Franz");
 team1.addNode(member1);
}
void draw(){
 background(100);
}
class Node{
 String name;
 Node(String pname){
   name=pname;
 }
}
class CircleMap{
 Node[] circleMapNodes = new Node[0];
 String mapName;
 CircleMap(String name){
   mapName = name;
 }
 void addNode(Node nodeToAdd){
   circleMapNodes = append(circleMapNodes,nodeToAdd); //doesn't work
   //circleMapNodes = expand(circleMapNodes); //doesn't work either
 }
}

thanks, you saved my day!
