spawnFunction does not work when compiled to JavaScript

[sethladd]

Consider this code:

import 'dart:html';
import 'dart:isolate';

void main() {
  var elem = query("#sample_text_id");
  var port = spawnFunction(runInIsolate);
  port.call('go!').then((msg) => elem.text = msg);
}

runInIsolate() {
  port.receive((msg, SendPort replyTo) {
    replyTo.send('hello from isolate');
  });
}

This works in Dartium, but not when compiled to dart2js

I've attached the necessary files. Please unzip and then run 'pub install' to clean up all the symlinks.

Using Dart Editor version 0.4.3_r20515

When I open the console in Chrome, I see:

Uncaught ReferenceError: window is not defined

This is actually a duplicate of https://code.google.com/p/dart/issues/detail?id=8455. An easy workaround for now is to avoid web workers by using 'spawnDomFunction' instead of 'spawnFunction.

Added Duplicate label.
Marked as being merged into #8455.

Thanks for de-duping. spawnDomFunction doesn't run concurrently (as is my understanding...)

Indeed, spawnDomFunction does not work concurrently. Nor is spawnFunction without web workers.
