I just upgraded to phpStorm 4 and javascript code complete has gotten worse

Hello, Gary,
Sorry for the late response.

Currently there is no such option in configuration, but you can explicitly annotate your factory function with return type Object, something like this:

/**
* @param proto
* @return {Object}
*/
function buildObject(proto) { /**/ }

Sorry, Konstantin, for the delay. Here is the file - I narrowed it - the problem is with this keyword. See the comment at the end:  - try to code complete this.m - only meth3 is prompted. I cannot move to 4 if this is not fixed (I'm still on 3, probably too late to ask for money back for upgrade :) ).

c )= {
    Prototype_CONSTR:function() {},
    /**
     * @param proto, props
     * @return {Object}
     */
    nowp:function (proto, props) {
        this.Prototype_CONSTR.prototype = proto;
        var o = new this.Prototype_CONSTR();
        if (props) {
            $.extend(o, props);
        }
        o.proto = proto;
        return o;
    }
}

t = {};

t.prot1 = {};

t.obj1 = c.nowp(t.prot1,{
    prop1:'aaa',
    meth1:function() {
    }
})

t.obj2 = c.nowp(t.obj1,{
    prop2:'bbbb',
    meth2:function() {
    }
})

t.obj3 = c.nowp(t.obj2, {
    meth3:function() {
        /// if you press ctrl + space, only meth3 is prompted, however, meth2 and meth1 are in the hierachy
        this.m;
    }
})

Javascript completion tried to become smarter in 4.0 and it suggests only relevant options. But eventually it is not smart enough is some complex cases, i.e in yours. I don't know how to workaround this in 4.0, but in 5th version you'll be able to help completion processor with @extends annotations:

/** @extends t.obj1 */
t.obj2 = c.nowp(t.obj1,{ //...



/** @extends t.obj2 */
t.obj3 = c.nowp(t.obj2, { //..

Please try 5.0 EAP (which will be very soon) and let me know how this works for you.
