using @Query about babel-plugin-angular2-annotations HOT 2 CLOSED

Thanks for reporting! QueryList<RouterLink> is causing it. You can safely change it to QueryList.

With TypeScript compiler, the following TypeScript code:

@Component({ selector: 'linkActive' })
export default class LinkActiveDirective {
  constructor(@Query(RouterLink) routerLinks: QueryList<RouterLink>) {
  }
}

is compiled into:

LinkActiveDirective = (function () {
    function LinkActiveDirective(routerLinks) {
    }
    LinkActiveDirective = __decorate([
        core_1.Component({ selector: 'linkActive' }),
        __param(0, Query(router_1.RouterLink)), 
        __metadata('design:paramtypes', [core_1.QueryList])
    ], LinkActiveDirective);
    return LinkActiveDirective;
})();
exports_1("default", LinkActiveDirective);

The line __metadata('design:paramtypes', [core_1.QueryList]) means that the generic type is only for TypeScript to check types but does nothing for metadata.

Currently babel-plugin-angular2-annotations is emulating what Traceur compiler did on generic types. I'll make it ignore generic types and show warnings, and write about this in README.

Thanks. Works after removing .

Throwing a warning would be helpful for people starting with Typescript and ES2015. Its a bunch of new stuff to learn and it is always good to have quick ways to get to the right info.
