Trivial fix for issue 4067, UiBinderGenerator is not stable. Miguel
would have fixed this earlier, but thought that the values from domId
were being used directly as, well, DOM ids. Actually they name Java
fields which will hold dom ids at runtime, generated by calls to
com.google.gwt.dom.client.Document.get().createUniqueId().

Manually tested stability via diff of generated code
