Description NukemBy 2014-03-01 17:05:45 UTC 
This is sub-case from  https://netbeans.org/bugzilla/show_bug.cgi?id=242344 (2014-02-26 20:47:23 UTC, #(2.1) ) which, hopefully, can be fixed quicker.

Occurs in Dev (Build 201403010001).

var myLib2 = new function MyLib2() {
    /** 
     * My Class
     * 
     * @constructor
     * @type MyLib2.MyLibClass
     * @returns {MyLib2.MyLibClass}
     */ 
    function MyLibClass() {
        /** @member {string} JsDoc for classMember */
        this.classMember = "member";
    };
    
    // make my class publically accessible
    this.MyLibClass = MyLibClass;

    /**
     * Builder of MyLibClass
     * @returns {MyLib2.MyLibClass}
     */
    this.makeMyLibClass = function () {
        return new MyLibClass();
    };
};

// (1) Intellisense does NOT suppose 'MyLibClass' after myLib2
var objViaNew = new myLib2.MyLibClass();

// (2) Intellisense does NOT suppose 'classMember' after objViaNew
var tmp = objViaNew.classMember;

// (3) Intellisense works CORRECTLY when object is constructed via builder method
var objViaMake = myLib2.makeMyLibClass();
var tmp = objViaMake.classMember;

// (4) Intellisense on instance variable 'objViaNewWithType' works CORRECTLY 
//     when variable from case #1 explicitly annotated with @type.
/** @type MyLib2.MyLibClass */
var objViaNewWithType = new myLib2.MyLibClass();
var tmp = objViaNewWithType.classMember;

Comment 2 NukemBy 2014-03-01 19:11:54 UTC 
I suppose the root cause for that problem is naming conflict which somehow appears in NetBeans between "this.MyLibClass" and "function MyLibClass". In valid JS these names exist in different contexts and should not intersect, but NetBeans currently fails when name of the variable within 'this' is the same as name of the function. See attached screenshot.

Problem does no occur with following code:

var myLib2 = new function MyLib2() {
    function _MyLibClass() {};
    
    this.MyLibClass = _MyLibClass;
};

or

var myLib2 = new function MyLib2() {
    function MyLibClass() {};
    
    this._MyLibClass = MyLibClass;
};

Reproducible, I'm going to look at this.
