Properties generated from plural form of messages does not have the exact values

Originally reported on Google Code with ID 7033

Found in GWT Release (e.g. 2.4.0, 2.5.0 RC):
2.4.0


Encountered on OS / Browser (e.g. WinXP, IE8-9, FF7):
Linux/Mac


Detailed description (please be as specific as possible):
Shortest code snippet which demonstrates issue (please indicate where
actual result differs from expected result):

Followed the example on http://code.google.com/webtoolkit/doc/latest/DevGuideI18nPluralForms.html#ExactValues
 - change class to interface
 - add a '}', and removed the ','
 - add Generate annotations
The finale file looks like this:

import com.google.gwt.i18n.client.Messages;
import com.google.gwt.i18n.client.LocalizableResource.Generate;
import com.google.gwt.i18n.client.LocalizableResource.GenerateKeys;

@GenerateKeys("com.google.gwt.i18n.rebind.keygen.MD5KeyGenerator")
@Generate(format = "com.google.gwt.i18n.rebind.format.PropertiesFormat")
public interface MyMessages extends Messages {
  @DefaultMessage("There are {0,number} items in your cart.")
  @AlternateMessage({
      "one", "There is 1 item in your cart.",
      "=0", "Your cart is empty."}
  )
  String cartItems(@PluralCount int itemCount);
}

Build the project, and we get the generated properties.

# Generated from package.MyMessages
# for locale en

#0=itemCount (Plural Count)
27565F45701C96702BC47C35BE474252=There are {0,number} items in your cart.

I am expecting to have this line as well:
cartItems[\=0]=Your cart is empty.

This is a general problem with @AlternateMessage.
Selectors are also not exported.

You are probably generating only the "default" locale, which doesn't have plural forms.
 Try using a real locale, such as:

@Generate(format = "com.google.gwt.i18n.rebind.format.PropertiesFormat",
    locales = ["en_US"])
@DefaultLocale("en_US")
public interface MyMessages extends Messages {
...

and then of course you have to build including the en_US locale (substitute whatever
locale your messages are written in).  For development, you can include
  <extend-property name="locale" values="en_US"/>
  <set-property name="locale" value="en_US"/>
  <set-property-fallback name="locale" value="en_US"/>
in the module you use for development.

Thanks for the answer - it works for plural forms! (but isn't =\d the way plural forms
are supported in the default locale? Shouldn't properties named cartItems[\=0] and
cartItems be created?)

The selectors are still not exported. For example:

@DefaultMessage("None")
@AlternateMessage({
  "ANY", "All events",
  "AGGREGATED", "Groups only",
  "UNAGGREGATED", "Singles only"})
String aggregateStateDisplayName(@Select AggregateState state);

Yields:

# 0=state (Selector)
aggregateStateDisplayName=None

I haven't had time to setup a repro case, but just looking at it I think the issue is
using the old PropertiesFormat rather than PropertyCatalogFactory (docs probably need
to be updated).

Perhaps there should be a warning when generating an output file using an old-style
MessageCatalogFormat if anything is present in any of the messages which can't be represented
in that API.

Thank you!!

@Generate(format = "com.google.gwt.i18n.server.PropertyCatalogFactory")
solved it.
And plural forms now work for the default locale as well!
