You have .gwt-Button in the .css file, but not in the style interface,
hence the compile error. It should be a clearer error (if you stop/start
dev mode it will probably give you the correct error, and it certainly will
if you GWT-compile the project)
In any case, to fix, you need to declare .gwt-Button as '@external'
@external gwt-Button;
.gwt-Button {
....
}
http://code.google.com/webtoolkit/doc/latest/DevGuideClientBundle.html#External_and_legacy_scopes
Now, you could create an accessor method in the Style interface for
gwt-Button, and use setPrimaryStyleName() on the buttons you want it appied
to. This way the style would be obfuscated. However when working with the
stock GWT widgets, its generally better to use un-obfuscated style names,
as currently, the 'dependent style names' system does not work with
obfuscation.
