Re: No source code is available for type java.lang.NoSuchFieldError
In your GWT console double click the individual errors and you should get a more detailed stack trace. It likely is something wrong with your code rather then a missing import/resource. I've gotten a similar error in the past and it's not overly intuitive.

Thanks for the idea - right now I'm strictly command-line (on a remote server) but I'll add this to my list of Reasons to Develop on My Local Machine with a GUI. :) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
