What steps will reproduce the problem?

1. Click Help menu > Online Guide

What version of the product are you using? On what operating system?
Dart Editor version 0.2.6_r15355
Ubuntu 12.04.1 LTS

Please provide any additional information below.

I've re-tested with the newest version. I'm still getting the dialog but it doesn't look like the exception appears anymore.

Dart Editor version 0.3.5_r18300
Ubuntu 12.10
java version "1.7.0_09"
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)

Re-opening case. Thanks for the information. I think that the cause of this is the version of Linux you are on. Are you able to open up any of the other links from the Editor? Have you tried setting a default browser in your OS and trying again?

I'm not able to open any links apparently. Running launches Chromium/Dartium as expected. Dart2js runs does actually throw the previously written exception. There's a default browser set on my system (Chrome).

I wrote a quick java program to launch a URL in the default browser. When run, it correctly launches Chrome showing google.com. It's not using the eclipse classes but shows that java is able to launch the default browser.

This seems to be caused by not having firefox installed. As a workaround I made a symlink (/usr/local/bin/firefox -> /usr/bin/google-chrome), restarted Dart Editor and all links seems to open.

I'm seeing a related problem: on an Ubuntu system with both Chrome and Firefox installed, and Chrome is the default application for opening html files, Dart Help opens in Firefox. Eclipse Help opens in Chrome, so it's a Dart Editor-specific issue, not a misconfiguration on my system.

Attached is a screen shot of the Eclipse Web Browser preferences on my system, showing the correct configuration. More importantly, it looks like adding the module that manages this preference will both fix this Dart Editor problem, and add a nice feature that's generally useful for any any app based on Eclipse.

Bumping M4 issues to M5- highest priority for me up through M4 release is the Analysis Engine implementation and performance.

Assigning to you since I don't have a machine to reproduce.

I can reproduce this on my linux desktop at work - the default browser for ubuntu (Cinnamon) is Chrome, but Dart Editor/Help/Online Guide opens in Firefox.

I know I'm late, but I am having this same problem. Just downloaded Dart package. Am running Xubuntu 13.04, Chrome is the default browser. I get the "Unable to open web browser on {0}" message. Any fixes?

Note: I moved the dart/ folder to /usr/local/dart/

This was fixed recently by Konstantin. Our next builds should include the bug fix.

I have just experienced this in Dart editor 1.2.0. Possible regression?
