Dart Plugin: Debugging dart code using Dartium from a page loaded from GAE dev server Follow

When I configure and start a GAE dev server debug configuration debugging a dart app does not seem to work: ie breakpoints are not observed. Loading the page directly into the browser is fine, btw, so the jb extension is installed fine, I guess.

Also, I've set the break points in both the original source and the version accessed via "scripts" tab in the javascript debugger instance.

Is this a bug/limitation or have I missed some config somewhere?

thx

Richard.
