typescript/JS module pattern. splitting into multiple files

Question

Please see the code below .

module AAA {
    export module user {
         export var am  = {}
    }
}

//1.
module AAA {
    export module user {
       am['x']= 'y';
    }
}

//2.
module AAA {
    export module user {
       user.am['x']= 'y';
    }
}

I am trying to split a module into two (or more) files. first (1.) form doesn't work, as the code generated sometimes (couldn't produce in playground) looks like (note the underscore)

var AAA;
(function (AAA) {
    (function (_user) {
        AAA._user.am['x'] = 'y';
    })(AAA.user || (AAA.user = {}));
    var user = AAA.user;
})(AAA || (AAA = {}));

but, second (2.) form works fine and I get intellisense for variable am . is this a reliable way, if I guarantee the order of files referenced? or do I need to refer from the root like, AAA.user.am['x']= 'y'; or a better way?

Also, in the generated code, there are two variable declaration var AAA; . Would this cause any issue. If I use a minifier, can it rid of it?

thanks.

This was a bug in the 1.0RC compiler. See this page where you can get a hotfix tsc.js file.
