Re: Chrome GWT Plugin required but is already installed

Thank you Jens. This would explain it. 

I can't find any way to downgrade Google Chrome on my mac. I don't appear to have a Google Software Update app as some webpage suggested I should. 

GWT 2.7.0 won't compile my application (2.6.1 has no problem). The error message is so cryptic there's no hope to figure out why. 

I've tried for 3 hrs now to get Super Dev Mode to work but the documentation is terrible so I can't figure it out. I'm hoping you can help with that since I'm out of options. 

I can't understand the GWT documentation on running SuperDevMode. It says:

If you are not using Dev Mode, first you need to compile the GWT application and launch a web server that serves its output files.

I don't know what that means. Are they suggesting that I simply create a standard war file and deploy that on a web server like Tomcat? 

The instructions on running the code-server are also lacking details. I've no idea how to launch this codeserver or set up my classpaths. I've tried using the maven gwt:run-codeserver goal and it does a bunch of compilation and looks to launch a server but when I visit the URL I get this error in my browser:


Problem accessing /. Reason:


and in the console I get:

Any ideas why this isn't working?

Latest Chrome on Mac OS is now 64bit but the browser plugin is only 32bit so it does not work anymore.

You can:
- downgrade your Chrome to version 38 and turn off auto update
- use Firefox 24 ESR or 26 (GWT plugin does not work in newer versions of Firefox)
- instead of DevMode use SuperDevMode which does not require any browser plugins.
