Hi,

I am trying to instantiate web components directly from Javascript but the system does not find the public constructor. I'll put a simple example to show the context and the results:

HTML Template:

<polymer-element name="wc-foo" constructor="Foo" noscript>

Hello World!

</template>

</polymer-element>

HTML index:

<html>

<head>

</head>

<body>

</body>

console.log (window); // (1)

console.log (window.Foo); // (2)

var foo = new Foo (); // (3)

</script>

</html>

Console Results:

(1) I have checked the window object and it includes the constructor Foo: function (){return f(a)}

(2) I don't know what but window.Foo returns undefined

(3) ...And so, new Foo() fails: Uncaught ReferenceError: Foo is not defined

Someone can help me to understand whats is the problem?

Thanks.

Can you ask this on stackoverflow with a polymer tag so we can answer there? I bet other people in the future will be interested in the answer.
