Error when using decorator metadata

[thitemple]

I'm playing with TS and Aurelia, so I'm trying to use a decorator.

I have a class as follows:

import {bindable} from "aurelia-framework";

export class NavBar {
  title: string;

  @bindable router = null;
}

And the result javascript file is:

System.register(["aurelia-framework"], function(exports_1) {
    var __decorate = (this && this.__decorate) || function (decorators, target, key, desc) {
        if (typeof Reflect === "object" && typeof Reflect.decorate === "function") return Reflect.decorate(decorators, target, key, desc);
        switch (arguments.length) {
            case 2: return decorators.reduceRight(function(o, d) { return (d && d(o)) || o; }, target);
            case 3: return decorators.reduceRight(function(o, d) { return (d && d(target, key)), void 0; }, void 0);
            case 4: return decorators.reduceRight(function(o, d) { return (d && d(target, key, o)) || o; }, desc);
        }
    };
    var __metadata = (this && this.__metadata) || function (k, v) {
        if (typeof Reflect === "object" && typeof Reflect.metadata === "function") return Reflect.metadata(k, v);
    };
    var aurelia_framework_1;
    var NavBar;
    return {
        setters:[
            function (aurelia_framework_1_1) {
                aurelia_framework_1 = aurelia_framework_1_1;
            }],
        execute: function() {
            NavBar = (function () {
                function NavBar() {
                    this.router = null;
                }
                __decorate([
                    aurelia_framework_1.bindable, 
                    __metadata('design:type', ) // ERROR, MISSING SECOND PARAMETER
                ], NavBar.prototype, "router");
                return NavBar;
            })();
            exports_1("NavBar", NavBar);
        }
    }
});

As you can see, the method call to __metadata is missing a second parameter. If I pass the keyword Object as a second parameter, the code works.

I'm using TypeScript version 1.7.0

[mhegazy]

which version specifically are you suing, what does tsc --version shows?

this looks a lot like #4364 which was fixed last week.

[thitemple]

When I type tsc --version inside my project folder it says: 1.5.3

I have TypeScript installed locally in my project and the package.json says 1.7.0, I installed today using

"devDependencies": {
  "typescript": "Microsoft/TypeScript"
}

[mhegazy]

use npm install typescript@next this will get you the nightly release. your dependency declaration will get you the last major version shipped which is 1.5.3.

here is the latest nightly version:

tsc --v
message TS6029: Version 1.7.0-dev.20150830

[thitemple]

I tried to install typescript@next and got the following error. Any idea why?

[mhegazy]

looks like the location on disk is locked by some other process. i would try restarting :)

[thitemple]

Ok. Now I'm running version 1.7.0-dev.20150830.

I recompiled the project and I had the same result.

[mhegazy]

@sheetalkamat can you take a look.

[sheetalkamat]

Looking into it now.
