spawnUri in dart2js does not generate the corresponding .dart.js file.

I'm running Dart Editor version 0.8.10_r30107 (STABLE) and Dart SDK version 0.8.10.10_r30107.
I saw issue #9422 been fixed and gave my sample code a try.However,It doesn't work in dart2js. I found the dart2js compiler did not generate the corresponding '.dart.js' file and the chrome dev tool console output:
Failed to load resource: the server responded with a status of 404 (Not Found) http://127.0.0.1:3030/spawn_uri/web/xxx.dart.js

After i manually run 'dart2js --out=xxx.dart.js xxx.dart' cmd under my source code directory and run the sample code again, it finally works.
Maybe it has something to do with Issue #8440?

P.S. main.dart has such a code line,
Isolate.spawnUri(Uri.parse("worker.dart"), [], response.sendPort);

Run html file via 'run as javascript' in dart editor and you will find such new generated files:
+main.dart.js
+main.dart.js.deps
+main.dart.js.map
+main.dart.precompiled.js
But it does not automatically generate such files,
-worker.dart.js
-worker.dart.js.deps
-worker.dart.js.map
-worker.dart.precompiled.js
Or just importing worker.dart into main.dart file and generate a single .dart.js file as a whole.

Not sure if dart2js, or isolate issue.

hi,it's an isolate issue,because i tested other codes without using spawnUri() and it worked.

You need to compile worker.dart yourself.

Reopening and assigning to the Editor team. Maybe there are ways to make this easier.

It would be cool to right-click on a .dart file and run dart2js on it.

We can probably punt to pub build for this (which, at this moment, doesn't compile the worker script, but it could/should)

I opened https://code.google.com/p/dart/issues/detail?id=16210 to track.

Removed this from the Later milestone.
Added this to the 1.4 milestone.

With the editor now supporting pub serve and pub build, and being able to configure dart2js through pubspec, the user can compile to js as needed.
