Re: Using custom LocalMessages apart from Locales

You'll have to make factories/providers of your Messages/Constants interfaces, that you'll switch using deferred binding on the "other" property.

interface MyMessages extends Messages { … }
interface MyMessagesFactory {
  MyMessages get();
class Dist1MessagesFactory implements MyMessagesFactory {
  interface Dist1Messages extends MyMessages {
    // empty, only there for GWT to look for dist1-specific properties files
  public MyMessages get() { return GWT.create(Dist1Messages.class); }
// similar for dist2 and dist3

Using deferred-binding, you'll <replace-with> MyMessagesFactory with one of Dist1MessagesFactory, Dist2MessagesFactory or Dist3MessagesFactory; and each one is using a "specialized" MyMessages interface with its set of properties files.

(you can of course use a generator with <generate-with> for MyMessagesFactory to automatically generate all specific implementations, instead of coding them by hand and using a <replace-with> rule)
