Thanks Martin for your reply!
Using your suggestions I was able to simplify the Wicket code to two
classes: a custom DropDownChoice and a renderer. As a drawback I had to
optimize/cache query in my service returning country name by ID/code.
One thing is not clear for me. How can I get a current locale in
CountryChoiceRenderer (without pass it from my DropDownChoice component)?
