IDE log

Please try following in JS file:


==== file.js =====
var rockband = {
    frontman : "Joe",
    "guitar" : "Jim",
    "solo": "Jack",
    "guitar#2" : "Jim2",
    albums : {
        "album1" : {released : new Date(), ready: 1},
        "album2" : {released : new Date(), ready: 1}
    }
};


function Folkband(){
    this.name = "";
    this.popularity =1;
    this.play = function(){}
}

Folkband.prototype.worth = 100;

/**
 * 
 * @param {rockband} o
 * @param {Folkband} b
 * @returns {undefined}
 */
Folkband.prototype.pokus = function(o,b){}

var e=  new Folkband(); e.pokus({}, {});

==== file.js end  =====


Now if you invoke cc in position of "|" in
  e.pokus({|}, {});

it will offer properties of both, rockband and Folkband and the code completion in the 2nd parameter is not offering anything.



Thank you
