Re: a mistake when set backgroun-color value

It's not a bug. Or at least, it's not a bug in GWT. This is the way CSS works with javascript...whenever you set styles in javascript you must use camel case, and in a css file you use hyphens. GWT was trying to stop you from making a mistake by pointing out that you had a hyphen in your css which is incorrect.

It's a pain, but it's not GWT's fault.
