getting Uncaught DOMException about flyer.js HOT 1 CLOSED

Hey Matthias,

Looking over the issue, I wonder if it has something to do with tighter restrictions on cross-origin messaging.

By default, the postMessage that i'm performing on each frame is assigned to all targets and this is usually frowned upon or not recommended to use for potential security reasons.

The code snippet you mentioned within the clojurescript codebase is here: https://github.com/benzap/flyer.js/blob/master/src-cljs/flyer/storage.cljs#L17

By setting this to undefined, you prevent the frames from being sent a message. I've had issues with this in the past with IE8, and i'm not sure if it's a problem with the pages not being loaded fast enough. However, it might be an issue with the introduction of tighter restrictions when posting messages between different domains.

A possible solution would be to be explicit with your origin when you're sending a broadcast.

So you would change this in domain B:

flyer.broadcast({ channel: "test", topic: "some.topic", data: {} });

to include the target domain:

flyer.broadcast({ channel: "test", topic: "some.topic", data: {}, target: "http://domain-a.somehost.com" });

Hope this helps, and thanks for the feedback!
