If it's from the same origin, you don't need postMessage. postMessage was specifically made for cross-origin communications. See http://dev.w3.org/html5/postmsg/#web-messaging and http://www.whatwg.org/specs/web-apps/current-work/multipage/web-messaging.html#web-messaging for the spec, and http://html5demos.com/postmessage2 for a demo. You will need to implement some JSNI methods in order to accomplish this in > GWT. or use Elemental. I doubt it'll solve Laurent's use case though: he was talking about loading a third-party site, and never mentioned that site was "friendly" to the "calling GWT app" (he used Google as an example) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
