Getting app to launch in Chromium using Dart Editor

Issue

I wanted to know if anyone is having trouble getting Cmd-r to launch their app?

It does bring up chromium, but I must then manually type localhost:3030 and then navigate to my actual app. Furthermore even after navigating to the app, the server connection eventually times out with

java.net.ConnectException: Connection refused

I am on a OS X 10.7.5, Dart Editor version 0.4.2_r20259. Thank you.

4/25/2013: Just to add details about what does not work, here is the error I get when I attempt to compile with the pre-release dartEditor mentioned by Devon Carew:
