Breakpoints not working in dart editor

I cannot get breakpoints working in the Dart editor. I'm using a launch configuration to point to a URL for a local MVC3 site. Debugging is enabled. Oddly enough, dart editor will break on exceptions and come into focus, but completely ignores breakpoints. I've tried 32-bit dart editor with 32-bit jre, and 64-bit dart editor with 64-bit jre to no avail.

I think that the launch configuration needs to use a Dart Editor supplied url:port rather than a custom URL in order to use debugging. My understanding is that this is how the two parts communicate (but I may be wrong). - Chris Buckett
What I found interesting is that there is communication between dartium and the dart editor because it will break on exceptions, just not on breakpoints. - w.brian
Could you post a minimum working example? I'll paste it into mine to see if I can reproduce the problem. I'm also using the newest version. - Ugtemlhrshrwzf
It's hard to post an example because you have to reproduce the environment, which is an MVC 3 site being hosted by the Visual Studio http server, although I suspect this issue is present regardless of what http server is used. My run configuration is using Dart VM, URL http://localhost:62939, run in checked mode, enable debugging. Like I said, dart editor breaks on exceptions, so dartium and dart editor are communicating. I think the best first step is to replicate my run configuration using a URL pointing to a locally hosted dart app and seeing if this issue is easily reproduced. - w.brian
I have a similar setup and was experiencing the the same symptoms (DartEditor ignoring breakpoints but showing source on exceptions) until I discovered that the html script tag was using an old src path, so the more recent dart app was never being downloaded. This is an odd behavior; the old (non-existing) dart app was executed even though the server returned 404. There may possibly be some misguided caching going on in Chromium and/or DartEditor. - Magnus Johansson

I think you're running into this issue:

http://code.google.com/p/dart/issues/detail?id=3748

Basically, we're trying to set breakpoints based off the URLs of our internal localhost:3030 server, but the browser can't resolve those as the content is being loaded from a different url.
