Adding multiple locales to TwitterTrends mobile sample - not working

Question

Hi All,
I have been having trouble adding support for muliple locales in my application so I desided to try it out with TwitterTrends sample application. Should be easy, but not working for me...
What I did:
1. Add locale folder under assets with an en_US sub folder
          src/assets/locale/en_US
2. Create a properties file for en_US and save to src/assets/locale/en_US
     src/assets/locale/en_US/twittertrends.properties
3. Add a single resource key for the home view in 'twittertrends.properties'
     views.home.title=Twitter Trends
4. Update the TwitterTrendsHome.mxml to use fetch the title from the properties file
     title="{resourceManager.getString( 'twittertrends', 'views.home.title' )}"
5. Add the locale folder to the applications source path, I did this by modifying the additional compilter args for Flash Builder:
     -locale en_US -source-path=assets/locale/{locale}
Result:
No title is displayed..
I am not sure what I did wrong. Any help is much appreciated.
Has anyone else seen/not seen this issue?
Cheers,
Greg

Try adding
<fx:Metadata>
    [ResourceBundle("twittertrends")
</fx:Metadata>
The problem is that the compiler isn't smart enough to tell that you're using the 'twittertrends' resource bundle unless you tell it so via [ResourceBundle] metadata. It doesn't try to analyze the ActionScript code inside of databinding expressions to determine what parameters you are passing to ResourceManager functions, etc.
If instead of databinding you use the @Resource() compiler directive, as in
title="@Resource('twittertrends', 'views.home.title')"
then it should be able to figure this out without the [ResourceBundle] metadata. But this way of doing it doesn't support switching the locale at runtime.
