Description Vladimir Riha 2013-08-15 13:52:31 UTC
Please try this in JS file:

 * @returns {Runner}
function test() {
    var b = new Runner();
    return b;

var a = test();

function Runner(object, name, dispose) { = name;
    this.notify = function() {

=> Navigator shows that test() returns either Runner or windows.test.b and the same goes for type of "a" variable

Vlado I see in navigator that the test() function and a variable is the type Runner. I have created test for it: and the structure file is:

Comment 4 Vladimir Riha 2013-08-16 06:48:01 UTC
I'm sorry, it depends on having some JS library in project (I'll attach the project to reproduce it). The library also defines global function test() without return value. But please notice that in file newjavascript.js, type of variable v is either Runner or windows.test.c (so both of this types comes from test() in newjavascript.js file, not from the one in folder qunit). So the type of variable v should be Runner|undefined ?

I see the problem is that there is defined in project windows.test object.
Comment 7 Petr Hejl 2016-07-19 14:41:52 UTC
Still reproducible.
