ok than back to using umbraco.library.GetDictionaryItem("Phone")

I have tried 

IDictionaryItem item = ApplicationContext.Current.Services.LocalizationService.GetRootDictionaryItems().First(x => x.ItemKey.Equals(key));

as an alternative, but I get the same sequence contains no elements error.

And I tried

 bool exists = ApplicationContext.Current.Services.LocalizationService.DictionaryItemExists("Jaar");

and I also get the sequence contains no elements error.

And I tried

IDictionaryItem item = ApplicationContext.Current.Services.LocalizationService.GetDictionaryItemById(21);

and I again get the sequence contains no elements error.

Am I missing something? I have a dictionary with actual words and translations.

This does work:

UmbracoHelper helper = new UmbracoHelper(umbracoContext);
 var dictionaryValue = helper.GetDictionaryValue("Jaar");

..but I want to programatically get translations for different languages and this solution won't let me do that. It always returns the translation of the "current" language (probably based on the umbracoContext).

I ended up writing this to get Dictionart Items based on key and ISO code

public static String ItemForKeyAndLanguage(String key, String languageCode)
{
            ILanguage language = ApplicationContext.Current.Services.LocalizationService.GetAllLanguages().First(x => x.IsoCode.Equals(languageCode));
            Dictionary.DictionaryItem dictionaryItem = new Dictionary.DictionaryItem(key);
            return dictionaryItem.Value(language.Id);
}

Same here. LocalizationService just keep giving me "sequence contains no elements"

Umbraco 6.1.6

The bug has been aknowledged, here's to hoping it will be fixed soon :-)
