I can`t do this work! I would like to use multiversion with separate files. Main execution should alert "1.1" and the "1.2", but I obtain "1.1" always. ¿Anyone know how to accomplish that? I'm lost... :-/

foo-1.1.js

(function(root){
  root.foo = {
		VERSION: '1.1'
	}
}(this));

foo-1.2.js

(function(root){
  root.foo = {
		VERSION: '1.2'
	}
}(this));

main.js

require.config({
  context: null,
	paths: {
		foo: 'foo-1.1'
	},
	shim: {
		foo: {
			exports: 'foo'
		}
	}
});

require(['foo'], function(foo){
	alert(foo.VERSION);

	require(['mymodule'], function(mymodule) {
		alert(mymodule.VERSION);
	});
});

define('main', function(){});

mymodule.js

require.config({
  context: 'test',
	paths: {
		foo: 'foo-1.2'
	},
	shim: {
		foo: {
			exports: 'foo'
		}
	}
});

define('mod',['foo'], function(foo) {
	return {
		VERSION: foo.VERSION
	}
});	

define('mymodule', ['mod'], function(module){
	return module;
});
