Answer 1

As the javadoc says DoubleBox is a ValueBox using a DoubleParser and DoubleRenderer. Those rely on NumberFormat.getDecimalFormat() which will trunk at 3 decimals in most (if not all) locales (for the default locale: http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/i18n/client/constants/NumberConstantsImpl.properties)

If you want another format, then use a ValueBox with a NumberFormatRenderer with your custom NumberFormat pattern (and either use the DoubleParser or make your own Parser with your custom NumberFormat pattern)
