GWT: Error in hosted mode after localization

I got some problems after making my gwt app "international".

my app.gwt.xml:

<module rename-to='app'>
    <!-- Inherit the core Web Toolkit stuff. -->
    <inherits name='com.google.gwt.user.User' />
    <inherits name="com.google.gwt.i18n.I18N" />

    <!-- Inherit the default GWT style sheet. -->
    <inherits name='com.google.gwt.user.theme.standard.Standard' />
    <!-- <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> -->
    <!-- <inherits name='com.google.gwt.user.theme.dark.Dark'/> -->

    <!-- Specify the app entry point class. -->
    <entry-point class='dk.blabla.app.client.Ent开发者_如何学编程ry' />

    <!-- Specify the paths for translatable code -->
    <source path='client' />
    <source path='shared' />

    <!-- Specify the locales you will be supporting -->
    <extend-property name="locale" values="da" />
</module>

And i added the folloing to app.html header

<meta name="gwt:property" content="locale=en"> 

Now I can not start my app in hosted mode. I get the following errors

[ERROR] [app] - Deferred binding failed for 'com.google.gwt.i18n.client.impl.CldrImpl'; expect subsequent failures

[ERROR] [app] Unable to load module entry point class dk.blabla.app.client.App (see associated exception for details) java.lang.RuntimeException: Deferred binding failed for 'com.google.gwt.i18n.client.impl.CldrImpl' (did you forget to inherit a required module?)

Edit:

By the way I am using eclipse with the google plugin.

I think you should add

<inherits name="com.google.gwt.i18n.CldrLocales"/>

to your app.gwt.xml. For detailed information see Runtime Locales
