some oo-problems i think:TypeError, x has no properties

    hi,
    i'm trying to make an array of objects, each changeable and easy to query, which is the reason i chose JS over regular max. everything worked fine on one onject, but with an array things go wrong, i'm propbably missing something basic; all my function calls give the same error as in the title. i'm using the o'reilly book, i know several people on here use it, so a pointer there might be useful. here's the code:
    //globals inlets = 1; outlets = 2; autowatch = 1; post("init");
    //netholder netsize = 100;
    var net = new Array(netsize); for (var i = 0; i < netsize; i++){ net[i] = new node(i); }
    //startnode function node(i){ }
    //create array in object node.connectArray = new Array(100);
    //adding a property to the object node.depth = 1;
    net[1].connectArray[1] = 1; var x = net[1].connectArray[1]; post(x);//error!
    i hope this isolates the problem clearly. btw is there a way to import code as in java? it's not very practical to have everything in a single textfile.
    any help of course greatly apreciated, thanks!

      Hi, Try 'this' instead ;)
      //globals inlets = 1; outlets = 2; autowatch = 1; post("init");
      //netholder netsize = 100;
      var net = new Array(netsize); for (var i = 0; i < netsize; i++){ net[i] = new node(i); }
      //startnode function node(i){ //create array in object this.connectArray = new Array(100); //adding a property to the object this.depth = 1; }
      net[1].connectArray[1] = 1; var x = net[1].connectArray[1]; post(x);//error!
